油液等效体积弹性模量βe的实验研究

Experimental Study on Equivalent Volume Elastic Modulus βe

针对目前液压系统油液综合体积弹性模量βe难以进行精确确定这一特点,采用对给定液压管路的压力脉动信号进行相关分析的方法,对液压系统油液综合体积弹性模量βe进行实验研究并找出了βe值随工作压力与油温的变化规律。

We experimentely studied βe, because it is difficult to set accurately the value of βe. In the study we used interrelated analysis method to given the pressure pulse signal within hydraulic pipe and found variation regular of βe value with working pressure and temprature.
