【Abstract】 To simulate the railway impact test process of tank container,a response spectrum analysis calculation is performed by fluid-structure coupling model,and a virtual quality method is used to deal with the liquid in the tank.The test indicates that the method is more practical than the transient calculation method and complies with the international standard requirements.With high accuracy and efficiency,the method can increase the successful possibility of the test and reduce the design cost of the product development.更多还原
