标准化动车组相关标准规定对样车的车窗（门）需进行交变气压载荷疲劳试验，以验证车窗（门）结构的疲劳强度。根据现有通用的车窗（门）气压疲劳实验装置，设计了另外一种新型的试验装置。本装置原理简单，操作方便，通用性能很强，能适用于不同的压力、频率、波形的试验条件，并可以采集到车窗（门）在交变载荷下的应变、形变值，为验证动车组车窗（门）在交变气压载荷下的疲劳强度特性提供了重要的试验手段。

The related standards of standardization of EMU require the window (door) in the train to withstand alternating pressure fatigue test, in order to verify the fatigue strength. In this paper, a new type of experiment device is designed based on the existing general pneumatic fatigue test device used for window (door) with the advantages of simple principle, convenient operation, and high applicability. Different test conditions of pressure, frequency and waveform can be realized and the strain and the deformation value of window (door) can be collected under alternating pressure. So this device provides an important test method to verify the fatigue strength of EMU window (door) under alternating pressure load.
