Otto Cycle

AIM: To write a program to generate a genetic algorithm in MATLAB. THEORY: A genetic algorithm (GA) is a method for solving both constrained and unconstrained optimization problems based on a natural selection process that mimics biological evolution. The algorithm repeatedly modifies a population of individual solutions.…

AIM: To create a 3D CAD model of the Planetary Gear System and to do motion analysis. THEORY: Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. [1] Typically, the planet gears are mounted on a movable arm…

AIM: To create a 3D CAD model of the IC Engine Valvetrain and to do motion analysis. THEORY: A valve train is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines)…

AIM: To create a 3D CAD model of the Piston Assembly and to do motion analysis. THEORY: A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made…

AIM: To create a 3D CAD model of the Internal Geneva Mechanism and to do motion analysis at different rpm. THEORY: The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into…

AIM: To write a program in MATAB to simulate the motion of a pendulum. THEORY: A pendulum is a body suspended from a fixed support so that it swings freely back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due…

AIM: To write a program to solve the Otto cycle in MATLAB and calculate the thermal efficiency. THEORY: An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle that is most commonly found in automobile…

AIM: To write a program to simulate the 2R robotic arm in MATLAB THEORY: A robotic arm is a type of mechanical arm, and is a part of Mechatronics. It is usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot.…
