摘　　要：平均推力测量是脉冲微推力器推进性能研究的关键问题之一。研究了在标准的周期性信号作用下,二阶系统的响应与输入之间的关系。在欠阻尼条件下,得到了系统稳态平均回复力等于平均推力的重要结论,仿真结果证实了结论。研究结果亦可应用于脉冲微推力器的总冲研究。Average thrust measurement is one of the key problems on studying propulsion performance of pulse micro-thruster.This paper investigates the relationship between response of second-order system and input signal with the input as standard periodic signal.On the underdamping condition,it is found that steady-state average restoring force equals to the average thrust.Simulation results validates this.The results can be applied to research total impulse measurement.
