Suspension system strength test method and device

The invention provides a suspension system test method and device. The method comprises the steps of: acquiring design parameters of a suspension system; constructing a finite element network model of the suspension system according to the design parameters; forming a coupling condition by using a first load applied from the body to the suspension system, a ground excitation load and an acceleration field when a vehicle is in different load states; loading the coupling condition to the finite element network model, and testing the strength of the suspension system to obtain a strength test result of the suspension system. Through the method, the strength test results of all parts in the suspension system structure and the deformation test result of the suspension system can be obtained, the time is saved, the workload of the test process is reduced, and the accuracy of the test results is improved. 本发明提出种悬架系统测试方法及装置，其中，方法包括：获取悬架系统的设计参数；根据设计参数构建悬架系统的有限元网格模型；利用车辆处于不同载荷状态下车身对悬架系统施加的第载荷、地面激励载荷以及加速度场形成耦合工况；将耦合工况加载
