Suspension Abuse Test Simulation using Modal Stress Recovery

Under driving condition, vehicles undergo various kinds of load, which consequently induces the fracture of automotive suspension system component. Not only to prevent these fractures but also to cut down cost and weight, it is important to predict load conditions and stresses at an early design stage. This paper covers the abuse condition that means extreme load condition such as pothole and curb strike. In this simulation, the limit behavior of car is considered, including non-linearity and large displacement of suspension system, and the method for simulating these events is described as an exemplary application using ADAMS.
