THE RESEARCH OF THE DAMPER CHARACTERISTIC TESTING METHOD ABOUT DAMPER IN VACUUM

摘要: 阻尼率是阻尼器的主要参数之一,需采用组合测试的方法进行测试。主要描述了适用于热真空环境下的阻尼器阻尼率测试系统的组成,测试阻尼器在热真空环境下不同转速、不同加载力矩的阻尼率,并针对热真空环境进行适应性设计,对测试及试验结果进行简单说明。

Abstract: The damper characteristic is one of the main parameters of damper and need to be tested by the combination testing methods.In this paper,the buildup of damper characteristic testing system applied in the thermal-vacuum environment was described.The damper characteristic was tested in different rotate speed and different loaded moment,and the adaptability design to the thermal-vacuum environment was carried out.In the end,the testing results were introduced briefly.
