Let us start by understanding in which field of Mechanical Engineering your interest lies before we dive deeper into the Mechanical Project Ideas. The subjects of Mechanical Engineering are majorly categorized into:
Fluid Mechanics is a branch of Mechanical Engineering that deals with the study of fluids at rest (fluid statics) and in motion (fluid dynamics). This study aims at understanding the behavior of fluids under several forces and atmospheric conditions.
Pressure of fluid at a point, the equation for pressure field, measurement of pressure, the force on an immersed surfaces, buoyancy, and stability are some of the major topics covered. Technological applications of fluid mechanics include rocket engines, wind turbines, oil pipelines, and air conditioning systems.
ANSYS, Sim Scale, Autodesk CFD are some of the widely used computational Fluid Dynamics software.
Machine design is the process of designing parts, components, and machines by selecting the right material, size, and shape in order to optimize the designed part. It is the most essential and primary activity in the mechanical industry. Machine design focuses on the following basic principles.
Mechanical Behavior – This includes taking statics, dynamics, the strength of materials, vibrations, reliability, and fatigue into consideration while designing.
Manufacturing processes – This includes considering manufacturing processes such as computerized machine control, engineering statistics, quality control, ergonomics, and life cycle analysis before starting the design process.
AutoCAD, CATIA, SolidWorks software are extensively used in Mechanical Design.
Solid mechanics studies solid materials’ behavior, motion, stressing, failure, and deformation under the action of forces, temperature changes, and phase changes.
The topics covered under Solid Mechanics are
- Stability of Structures – This includes examining whether structures can return to a given equilibrium after a disturbance.
- Dynamical systems – Deals with mechanical systems that are highly sensitive to their initial position.
- Vibrations of solids and structures – Includes examining vibration and wave propagation of vibrating particles and structures.
- Fracture and Damage Mechanics – Deals with crack-growth mechanics in solid materials.
- Composite Materials – Solid mechanics applied to materials made up of more than one compound like reinforced plastics, fiberglass, etc.
- Computational Mechanics – These are numerical solutions to mathematical equations that arise from various solid mechanics branches.
- Experimental Mechanics – Design and Analysis of experimental methods to examine solid materials and structures’ behavior.
Thermodynamics is the study of heat, work, temperature, and their relation to energy, radiation, physical properties of matter, and how thermal energy is converted to and from other forms of energy.
Classical thermodynamics, statistical mechanics, chemical thermodynamics, and equilibrium thermodynamics are the primary branches of thermodynamics.
This study deals with understanding the thermodynamic processes, which are categorized into:
- Adiabatic process – Occurs without loss or gain of energy by heat.
- Isenthalpic process – This occurs at a constant enthalpy.
- Isentropic process – A reversible adiabatic process that occurs at constant entropy,
- Isobaric process – This occurs at constant pressure.
- Isochoric process – Occurs at constant volume.
- Isothermal process – This occurs at a constant temperature.
- Steady-state process – This occurs without a change in the internal energy.
Kinematics and Dynamics of Machines
Study of forces responsible for the movement of a mechanism without considering the causes of motion. Machine Dynamics is the study of the cause of a machinery’s motion depending on the system’s forces.
Kinematics deals with the relative motion between various machines, whereas dynamics deal with the force and their effects while acting upon the machine part which is in motion.
Kinematic pairs are broadly divided into sliding pairs, turning pair, rolling pair, screw pair, and spherical pair, depending on the type of connection the mechanism’s elements have.
Manufacturing Technology is the study of manufacturing processes that are involved in manufacturing. The manufacturing processes in Mechanical Engineering are broadly classified into casting, molding, forming, machining, joining, and additive manufacturing.
Depending on the topic that interests you, it is now time to choose the project you want to work on.
Thermodynamics Project Ideas
Make an Air Compressor at Home
Air Compressor is a mechanical device that is essentially used to increase a fluid’s pressure by reducing its volume. Air Compressors work by forcing air into a container and pressuring it, which is later forced through an opening where the pressure builds up.
They are powered by an engine that turns electrical energy into kinetic energy. Either positive displacement or negative displacement can achieve air compression.
Learn more about Air Compressors and make one by yourself.
Make a Free Energy Steam Engine at Home
A steam engine is a heat engine that performs mechanical work using steam as the working fluid. The steam engine uses the force produced by steam pressure to push the piston back and forth inside a cylinder. This pushing force is transformed into rotational force by a connecting rod and flywheel.
Steam engines are external combustion engines as the working fluid is present externally and is separated from the combustion products. The steam engine is a reciprocating engine as it uses more than one piston to convert pressure into rotational energy.
The steam engines are divided into three general types, which are stationary (factory), locomotive (trains, cars), and marine (ships) engines.
Mechanical Design Project Ideas
Design a Car Wheel on AutoCAD
AutoCAD is a commercial computer-aided design and drafting software application that allows the drawing and editing of digital 2D and 3D designs.
The components of a car wheel are the tire, rim, and hub. The tire, which is the wheel’s width, goes around the rim and gives the wheel grip on the road surface. The hub is where the wheel attaches to the axle of a car. It is time for you to design one!
Create a Mechanical part using CATIA
CATIA is a solid modeling tool that incorporates CAD, CAE, and CAM. CATIA is a compelling software that allows sketching, designing, assembling, and drafting of models.
It is used to design, simulate, analyze, and manufacture products. It is the most widely used software by any mechanical engineer.
The market for Electric Vehicles is increasing at a profound rate with major players like Toyota and Tesla looking to set up production facilities globally to build a new market for electric cars and vehicles.
Manufacturing Technology Project Ideas
Mini Bench Tapping Machine Project
Bench tapping is a process that is used to make screw threads in a work-piece. Bench Tapping machine is a shaft-driven machine that consists of a strong frame to hold the tapping shaft in place.
Bench Tapping is also known as internal threading. The tap is used to cut out the female portion of the threading pair or the nut part. Two pieces of metal are fastened together, which helps in drilling a hole where screws are utilized.
The tapping machine helps in finishing several tasks by saving time and labor.
Kinematics and Dynamics of Machines Project Ideas
Make a Robotic Arm
The robot arm is a series of joints, articulations, and manipulators that closely resemble a human arm’s motion and functionality. The arm is the main section of the robotic arm and consists of three parts – the shoulder, elbow, and wrist.
These are all joints, with the shoulder resting at the arm’s base, typically connected to the controller, which either moves forward, backward or spins. The robotic arm is driven by gravitational, and inertia forces of the counterweight mounted on links.
The joints of the robotic arms rotate freely and do not have any actuators on joints. This project will teach you the kinematics and dynamics that are involved in designing a mechanism.
Fluid Mechanics Project Ideas
Tornado in a Bottle
Tornado in a Bottle is a simple project idea that relates three concepts of Fluid Mechanics and gives a practical understanding of the concepts involved in Fluid Mechanics.
Make a Hydraulic Lift
A hydraulic lift is a mechanism that is used to lift or move heavy objects. Hydraulic lifts work on a basic principle where the pump pushes oil into the cylinder to go up, which pushes the piston on which the objects are placed up.
The valve opens and the oil is allowed to flow back into the reservoir and is pushed back using the gravitational force of the object that is being lifted.
They are found in automotive, shipping, construction, waste removal, mining, and retail industries as they are the most effective means of raising and lowering people, goods, and equipment.
