摘要
采用有限元分析方法对一种压电式小推力测试系统进行热力学分析,计算出系统结构温度应力分布与变形情况,分析该变形对系统传感器输出的影响。通过试验对测试平台进行精确测试,得出实际情况下温度对测试系统的影响规律。综合理论与试验分析,找出解决温度影响方案。
Piezoelectric small thrust motor measuring system is analyzed through finite element analysis. The distribution of thermal stress and deformation of structure are calculated, and the influence of the deformation on system is further analyzed. The effect of temperature on the measuring system is obtained by experiment. Based on the analysis and experiment, a solution is proposed to eliminate the influence.
