Model Development and Analysis of Four Bar Mechanism

Abstract� Mathematical modeling / Simulation is a process of designing a model of a real system and conducting experiments with it for the purpose of understanding the behavior of the system. It is widely used for analyzing mechanisms also. Investigations of the various stages of mechanism design like synthesis and analysis using mathematical model is an effective tool by high development of computing technique, which enables complicated problems to be solved with minimum number of assumptions. Four bar mechanisms are widely used in automobiles and industrial applications. The present work aims at developing a computational environment for synthesizing and analyzing the mechanism both kinematically and kinetically. This work presents a simple and good mathematical model for getting the relevant parameters like link lengths, their velocities, their accelerations and the forces acting on it with the input of output function. The computational environment for the model is developed using a ‘Ch’ language, an embeddable C/C++ interpreter. The effect of varying parameters like link lengths, output functions on displacement, velocity, acceleration and forces has been studied.
