Technical Seminar Topics for Mechanical Engineering

In this section, we will discuss with you in detail about some seminar topics for mechanical engineering which are familiar to you or you have heard about them in the real world. These are the best topic to choose from as listening about something familiar engages the audience.

  • Aerial Photography Using Remote Controlled Flying Robot

This is one of the applications of Unmanned Aerial Vehicle (UAV). The general term for this is drones. For developing this kind of robot, a surveillance camera is attached to a lightweight drone. The drone is then controlled using a remote controller and the camera is also controlled remotely.

This is used by many photographers but it has a large scale military use. Solar panels are sometimes also attached to this drone for increasing its flight time.

 

  • Autonomous Car

The newest trend in the industry of automobile is the Autonomous Car. These are self-driving cars which are capable of sensing their environment and then driving by themselves. At the early stage, the speed of these cars was too less but with time engineers have worked towards increasing the speed and accuracy of these cars. Today, we see these cars running fully functional on the road and more and more people are getting attracted towards buying them.

 

  • Automatic Emergency Braking

This feature is installed in cars for applying brakes in emergency cases if driver fails to apply the brakes. This scans the road ahead and if there is a possibility of collision and driver fails to apply the brakes then this system automatically stops the vehicle.

  • Car Speed Control by Bluetooth

This latest technology is for the prevention of the accidents. This works on the Bluetooth installed inside the vehicles. If the separation distance between two vehicles becomes less than 100 meters then Bluetooth devices get activated. If the distance reduces further and comes down to 10 meters then the automatic braking system applies the brakes.

 

  • Supercharging in Automobile

This is for generating more power in the automobiles. In the process of supercharging, more dense air is supplied to the engine so that it burns more fuel generating more power.

 

  • Digital Manufacturing

This is the latest kind of manufacturing process centered mainly around a computer. This is becoming more and more popular day by day with the advancements in the computer industry.

 

  • Electronic Fuel Injection (EFI)

The EFI is used as an alternative to carburetor. A carburetor in a car mixes air and fuel. The EFI injects the fuel directly into the engine’s cylinder by using electronic controls. One of the most prominent advantages of the EFI is that it increases fuel efficiency. Other advantages include more consistent power, automatic altitude adjustment and easier starting.

 

  • Hyperloop Technology

This is a high-speed transportation system for both public and goods. This term mainly became popular because of Elon Musk. This works by sending specially designed capsules through a tunnel or tube maintained under partial vacuum. The proposed top speed of these capsules is about 760 mph.

  • Laser Cutting System

This uses lasers to vaporize the material and thus executes the process of cutting. This process is mainly in use because it is more efficient than the plasma cutting. The focused laser beam is directed directly towards the material which either then burns or melts down. This is blown by a high jet of gas leaving behind a polished and shiny cut out material.

 

So far we have discussed with you the technical seminar topics for mechanical engineering which involved indirect application of mechanical engineering. It means that these applications had other engineering field applications too apart from mechanical engineering.

In the next section we’re going to look at some mechanical seminar topics which will involve more visible application of mechanical engineering.

Mechanical Engineering seminar topics / Seminar topics for Mechanical Engineering 2022

This section is going to be very useful for you if you’re a student of mechanical engineering. In this section we’ll suggest you some topics for you seminar which are closely related with the field of mechanical engineering.

  • Advanced Rocket Motors

These are systems such that thy release the heat in the combustion chamber. This heat released has very high temperature which is greater than even the chambers of some nuclear power plants. Advanced rocket motors focus towards increasing the efficiency as well as thrust of the rocket.

Very limited information is available on the internet related to these engines. If you’re choosing this topic for your mechanical engineering seminar topic then make the decision wisely.

  • Benchtop wind tunnels

These are specially designed wind tunnels, which circulate the air inside a room only. These systems draw and expel air inside the room rather than recirculating it through a duct. There are wide ranging applications of benchtop wind tunnels from small scale application inside a laboratory for R&D to large scale applications in the field of aerodynamics.

Much information is available online about this and it could be used to get ideas for your seminar if you’re choosing this topic.

  • Ceramics Disc Brakes

Grey cast iron was used to make disc brakes till now. But with the help of new emerging technology, ceramic disc brakes have found their way inside the market. The disc brakes made with grey cast iron were heavy and reduced acceleration along with taking up more fuel. The new ceramic disc brakes are lower in price and are lightweight.

There are many advantages of ceramic disc brakes over carbon discs. You can have a look at them online.

  • High-Speed Precise Gear Boxes

These are developed to offer continuous or cyclic duty in high speed, high precision applications. The torque generated by these is very high and is somewhere between 14 and 2000 Nm. These are completely sealed and these can be installed in any kind of orientation.

  • Underwater Wind Mill

These are installed inside the ocean to harness the wave energy generated by the ocean water. The normal windmills use the flow of air or we can say the kinetic energy of the air to run the turbine. The underwater wind-mills use the kinetic energy of the ocean waves to run the turbine. Thus, another name given to these windmills is Tidal stream turbines.

  • Underwater Welding

Another known name for this kind of welding is Hyperbaric welding. This process of welding involves welding at elevated pressures and is normally done underwater. This kind of welding can take place both in a dry as well as in a wet environment. When in dry, this is done inside a chamber with increased level of pressure. The welding done in dry environment is named as Hyperbaric and that done inside the water is Underwater. In the hyperbaric welding, the conditions are more in the control as the environment is set up by welders only. This, in case of works requiring high precision, hyperbaric welding is used.

  • Pulse Detonation Engine

This is a propulsion system designed to use detonation waves for the combustion of the fuel. The application of this engine is in jets or in rockets. The engines currently in use inside rockets or jets combust the fuel at a subsonic rate. The pulse detonation engine is a concept which says that fuel will combust at supersonic rate providing more thrust.

The main problem with PDE is starting the detonation. The energy required to start the detonation in this type of engine is practically very high than compared with a normal engine.

  • Rijke Tube

This is a tube which is open at both the ends. Inside of this tube there is a heat source which converts heat into sound. This source does this by creating self-amplifying heat waves. The phenomenon on which Rijke tube works is known as Thermoacoustic effect.

If you’re choosing this topic as one of your seminar topics for mechanical engineering then you can start with explaining about the Thermoacoustic effect and then elaborate Rijke Tube as one of its applications.

  • Stirling Engine

This is a very basic type of engine which works on the expansion and compression of air. It converts heat energy into the mechanical work. In this engine, the gas is heated by the heat supplied by a cylinder placed outside of it. This heated gas is then shunted at a different location. This engine works in a closed cycle process. It has got many applications including some underwater applications too.

First due to its working it can be used as a heating or cooling device. It is also used for solar power generation, as a heat pump and in marine engines. This can be one good option in seminar topics for mechanical engineering as stirling engine has got widespread use.  

  • Dual Fuel Engine

These engines are fitted inside the ships. Dual fuel engine allow ships to be operated on either LNG or other conventional liquid marine fuels including LFO, HFO or liquid biofuel. These allow switch between fuels seamlessly without any loss in power or fuel.

Other type of these engines is the engines that operate on the mixture of two fuels. Generally, the mixture of diesel and natural gas is used. A special thing about these engines is that they can operate on single fuel too if the other fuel is unavailable.

  • Advanced trends in welding

To join two materials, the technique of welding has been in use from a long time. Improvements have also been made in this with time. The laser welding technology is to be used in a more automated way in the manufacturing industry. The robotic welding industry is also growing.

Choosing this topic as seminar topics for mechanical engineering can be beneficial for you in many ways.

First, welding is considered to be a primary thing in mechanical engineering field. Considerable amount of R&D is done to enhance the process of welding. Thus, this remains a hot topic at all times and you can gather much information about it for your seminar.

 

  • Automobile safety system

Automobile system has two different aspects, first there is the software aspect and then there is the hardware one. As we are looking at seminar topics for mechanical engineering, we will have a look at the hardware aspects only. This involves studying and practicing design, construction and minimizing the effects of collision on the vehicle.

 

As the vehicle manufacturing industry is also one of the most growing industries, thus this is also one of the topics where you can gather a lot more information.

 

  • Green Energy Technology

Green energy is generally the term used for the kind of manufacturing technology that is environment friendly.  This mainly refers to the process of producing energy using a renewable energy source such as windmills, solar energy, tidal energy and many others.

Renewable energy is something that we all have heard about and green energy technology can be seen as its implementation.

 

  • Tidal Energy

Tidal energy is a type of renewable energy which is produced by natural rise and fall of tidal waves. This happens due to the interaction between the gravitational forces of earth, moon and sun. The water is passed through a constriction to generate an intense flow of water and then it is harnessed to run the turbines.

If you choose this as one of your seminar topics for mechanical engineering, then you can talk about the tides as well as about the process of harnessing them to produce energy. Next, you can talk much briefly about the mechanism really involved and how this is environment friendly.

 

  • Laser beam machining

This process is used for removing the materials from metallic or non-metallic surfaces. This uses heat directed from laser beams to evaporate the material. As there is heat involved in this process, this is used for the materials with low conductivity.

 It is advantageous because the laser beams are monochromatic and these can be focused sharply even on the small surfaces. Also, the cost of maintaining the lasers is quite low as there is hardly any material wear and tear involved.

 

  • Laser Cutting System

This involves focusing a sharp beam of laser on a material which can penetrate through that material. This type of cutting is particularly in use these days due to many countable advantages of lasers. The laser beam is directed towards the material through optics.

Many things control the cut quality in laser cutting system but if kept under control, laser cutting is a very stable, reliable as well as accurate option for cutting.

As this involves a typical mechanism which brings in the use of optics and this is also in use these days, so this can be a better option in the list of your seminar topics for mechanical engineering.
