Analysis for Suspension Spring to Determine and Improve Its Fatigue Life Using Finite Element Methodology
The suspension system for a small sized car, especially for the front wheels, uses Macpherson struts. This system uses helical springs to offer resilient suspension system absorbing shocks during motion of the vehicle. The process of absorbing the shocks is brought about by storing and releasing the shock energy on a gradual time scale. The effort for this work would be to determine the fatigue life of the existing coil spring on the car and identify areas of improvement over the fatigue life. Finite Element Analysis would be deployed for the structural analysis using NASTRAN or suitable solver while the fatigue life would be predicted using `MSC Fatigue' or suitable. For this work, experimentation shall be performed for validating the performance parameter identified as `Stiffness' of the spring. The load vs. displacement shall be recorded using load cells with data logger to display results. The results of Experimental work shall be compared for results with the numerical methodology and vice-versa. The concurrence of the results shall offer validation for this thesis work. Variants shall be proposed for study and analysis. Recommendation shall be made at the conclusion stage of the work in terms of generic specs or configuration of the spring.
