Failure Analysis of Suspension System through Bond Graph

This paper presents the premature failure analysis of suspension system. This area of research has attracted attention of many engineers and researchers. The insufficient deflection is one of the major reasons behind the premature failure of suspension system of a passenger car. Deflection capacity under dynamic condition plays important role in the life of any suspension system. In this work a simulation model has been developed and presented which is capable of finding deflection of a suspension system. By simulating this model one may find deflection under the extremely riding condition at the time of design and manufacturing can be done accordingly. To know the reason behind premature failure one may again simulate the computational model using physical parameter of the system. Analyzing the simulated result one may conclude possible factor behind premature failure. Bond graph is a very good modeling technique in the multi energy domain. Paper includes simulation result for a car model after simulating computational model developed through bond graph technique on Symbol Shakti Sonata software.
