摘要
三线摆可以应用于电推进器微推力的测量。文章介绍三线摆微推力测量的原理,分析测量结构的阻尼特性及其影响,提出人为施加阻尼以缩短动态时间,并对外加阻尼作用下的测量系统进行分析,通过仿真和实验验证了阻尼控制方法的有效性。
During the development of electric thrusters, the trilinear pendulum are used to measure the micro-thrust. This paper, based on the principle of the micro-thrust measurement, firstly analyzes the damping characteristics of the trilinear pendulum measurement structure and its influence on the measurement result, then proposes a method applying external an damping to shorten the dynamic response time. The measurement system with external damping is analyzed. Lastly, the effectiveness of the damping control method is verified by simulation and experiment.
