Abstract

          Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels.

In this paper majorly the maximum stresses, and natural frequencies of the car-frontal Macpherson strut suspension system by using finite element method with different types of loading conditions are examined. Preliminary static analysis is done by assuming steady state operating conditions. The assumptions are smooth road way, constant speed cornering, and vehicle on a downhill grade. The load cases are carried out to estimate the maximum stresses and also stresses in X, Y, Z-directions

 

In dynamic analysis, the natural frequencies of frontal car-Macpherson strut suspension system are examined. And also comparing the natural frequencies of the system made with steel w.r.t. the system made with unidirectional-carbon epoxy material. The advantage of using advanced composites in this area is to produce more strength and simultaneously reduction of body weight. Carbon fiber can offer the same strength for just 25% of the weight. Finally the maximum stresses and natural frequencies of the system made with steel and unidirectional carbon epoxy composite material are compared.

Key words:  Suspension system, Structural, Model and Hormonic Analysis, Finite element Analysis.
