摘　　要：油液的体积弹性模量以及疲劳特性参数是油液非常重要的物理参数,在液压系统中,直接影响系统的稳定性和动态品质。研究设计了弹性模量及疲劳特性参数测试试验台,基于弹性模量的定义对弹性模量进行测量计算,同时以专用车辆油气悬挂装置为对象,对悬挂内液压油疲劳特性参数进行测试,如:温度、粘度等。完成控制系统以及数据采集系统的设计,与上位机实时通讯,实现测试过程的自动化。Hydraulic oil bulk modulus and fatigue property parameters are very important physical parameters in the hydraulic system, directly affects the stability and dynamic quality of the system. Based on the definition of the elastic modulus, the testing device for damping oil bulk modulus and fatigue characteristic has been designed, while using the oil gas suspension device of special purpose vehicle asthe testing object, where the fatigue characteristic parameters of hydraulic damping oil have been tested, such as temperature, viscosity. And the design of control system and data acquisition system are completed, timely communication with the host computer, the automatization of the test process is realized.
