Common car durability developing methods are firstly introduced, and then focus on simulation methods. Generally, there are two simulation methods to get structural stress in time-domain: quasi-static method and modal superposition method. The former cannot consider structural dynamic response while the latter can do, which is used to calculate car body stress and damage with fatigue curves. According to comparing results between test and simulation, results of modal superposition method has better consistency with test results than quasi-static method where local modes predominated. Furthermore, it is easy to use modal superposition method to search countermeasures without extra software and calculation resources, which has good application prospect.
