Frequency Analysis of a rotating shaft

Introduction: An object's natural frequency is the frequency or rate that it vibrates naturally when disturbed. Objects can possess more than one natural frequency and we typically use harmonic oscillators as a tool for modeling the natural frequency of a particular object. We can apply an unnatural or forced frequency…

Aim: To model and perform motion analysis on Valve Train   Introduction: A valvetrain is a component that is designed to open and close the intake and exhaust valves so that air/fuel mixture can enter and leave the combustion chamber as gases. Nowadays, engines are designed with overhead cam assemblies which are known…

Aim: To model and perform motion analysis with different piston positions   Introduction: 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…

Aim: To model and run a motion analysis on Planetary Gear System.   Introduction: An epicyclic gear train or planetary gear consists of 2-4 gears mounted so that the center of one gear revolves around the center of the other. The planet and sun gears mesh so that their pitch circles roll…

Objective : Use the given 2D CAD drawings to create the 3D model of the Internal Geneva Mechanism and perform motion analysis by rotating the driver wheel at (i) 10 RPM and (ii) 20 RPM. Calculate the results of the study with and without precise contact.   1. Introduction 1.1 Geneva Mechanism  Geneva mechanism,…

  PARSING NASA THERMODYNAMIC DATA   OBJECTIVES   1. Write a function that extracts the 14 co-efficients and calculates the enthalpy, entropy and specific heats for all the species in the data file. Here R is the universal gas constant, T is the temeprature 2.  Calculate the molecular weight of each…

GENETIC ALGORITHM The genetic algorithm is a method for solving both constrained and unconstrained optimization problems that is based on natural selection, the process that drives biological evolution. It repeatedly modifies a population of individual solutions. At each step, the genetic algorithm selects individuals…
