Abstract
The car body of high-speed train bears all the static and dynamic loads. An accurate strength analysis of critical point is crucial for its fatigue design. Since a fatigue analysis is dependent on the load amplitude and its application point on car body, the loads applied in the fatigue test is studied by using the strength test bench. A comparative study was performed among the relevant standards concerns the car body fatigue. In addition, a specific test scheme is promoted, and the applied loads on vertical, lateral, longitudinal and torsional directions on car body under various spectrums are thoroughly determined. This study provides a basic fatigue test bench of car body for high-speed trains with the specific loads application and test schemes. This allows the body to be subjected to random loads and provides a basis for the specifications of follow-up fatigue tests on the car body and its components.
