Motion Analysis of a Planetary Gear System

OBJECTIVE To perform motion analysis of a valve train. INTRODUCTION 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 injection engine) into the combustion chamber,…

OBJECTIVE To perform motion analysis of a piston assembly. INTRODUCTION A slider-crank linkage is a four-link mechanism with three revolute joints and one prismatic, or sliding, joint. The rotation of the crank drives the linear movement the slider, or the expansion of gases against a sliding piston in a cylinder…

OBJECTIVE To perform motion analysis of the planetary gear with a sun gear, a ring gear, a carrier and four planet gears. INTRODUCTION A planetary gear train (also known as epicyclic gear) consists of two gears mounted so that the centre of one gear revolves around the centre of the other. A carrier connects the centres…

OBJECTIVE To study the mode shapes and the critical frequencies of the shaft. INTRODUCTION Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force. The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of…

OBJECTIVE To perform motion analysis of an internal geneva mechanism. INTRODUCTION The Geneva drive is a gear mechanism that translates a continuous rota movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel (driven wheel) that…

OBJECTIVE To design and analyse a centrifugal pump. INTRODUCTION Centrifugal Pumps are the most popular and commonly used type of pump for the transfer of fluids using centrifugal force. These are the undisputed pump choice especially for delivering liquid from one location to another in numerous industries including agriculture,…

OBJECTIVE To model and simulate the flow of air through a flowbench. INTRODUCTION The internal combustion (IC) engine is designed to produce power from the energy that iscontained in its fuel and for the fuel to burn air(oxygen) is necessary. The quantity of air(oxygen) decides the quantity(power) and the quality(exhaust…

OBJECTIVE To illustrate the variation of lift and drag force with the angle of attack of an airfoil. INTRODUCTION Wings, horizontal tail surfaces, vertical tails surfaces, and propellers are all examples of airfoils. An airfoil is a device which gets a useful reaction from air moving over its surface. The component of…

OBJECTIVE To simulate flow over a cylinder at different Reynolds number. INTRODUCTION Flow over cylinders and spheres is frequently encountered in practice. For example, the tubes in a shell-and-tube heat exchanger involve both internal flow through the tubes and external flow over the tubes, and both flows must be considered…

OBJECTIVE To write a code in Python that parses the CONVERGE file containing the data of an IC engine. INTRODUCTION Otto cycle is the ideal cycle for spark-ignition reciprocating engines. It is named after Nikolaus A. Otto, who built a successful four-stroke engine in 1876 in Germany. In most spark-ignition engines, the…

OBJECTIVE To draw a curve that describes the variation of specific heat with the temperature at a constant pressure. INTRODUCTION Curve fitting is the process of constructing a curve or function that has the best fit to a series of data points. Curve fitting can involve either interpolation, where an exact fit to the data…

OBJECTIVE To find the minimum pressure required to break the ice of given thickness using cushion vehicle. INTRODUCTION When the ice pack in one section of the river, it hinders the flow of water and causing floods above the packed ice. Self-powered air cushion vehicles can be used successfully to break it. An experiment…

OBJECTIVE To solve the Ordinary Differential Equation (ODE) using Python and simulate the motion of a simple pendulum using ODE. INTRODUCTION Differential equations have wide applications in various engineering and science disciplines. In general, modelling of the variation of a physical quantity, such as temperature,…

OBJECTIVE To find the global maxima of the stalagmite function using the genetic algorithm in MATLAB. INTRODUCTION In mathematics, computer science and operation research, optimization is the selection of the best element (with regard to some criterion) from some set of available alternatives. In the simplest case, an…

OBJECTIVE To draw the PV diagram and find to the efficiency of an Otto engine. INTRODUCTION Otto cycle is the ideal cycle for spark-ignition reciprocating engines. It is named after Nikolaus A. Otto, who built a successful four-stroke engine in 1876 in Germany. In most spark-ignition engines, the piston executes four complete…

OBJECTIVE To write a code in Matlab that parses the NASA thermodynamic data file and then calculate thermodynamic properties of various gas species. INTRODUCTION Thermodynamic properties like Specific heat(Cp), Enthalpy(h), Entropy(s) are used in thermodynamic applications. These properties are dependent on temperature…

OBJECTIVE To solve the Ordinary Differential Equation (ODE) using MATLAB and simulate the motion of a simple pendulum using ODE. INTRODUCTION Differential equations have wide applications in various engineering and science disciplines. In general, modelling of the variation of a physical quantity, such as temperature,…
