摘　　要：本文以某型号激光惯组的减振系统为研究对象,说明了惯组在线振动激励时产生角振动的原因及影响因素,介绍了测量角振动幅值和计算角振动频率的方法并进行了试验,对试验测量结果进行了分析并与激光陀螺输出角速率进行比较,结果表明惯组振动输出角速率和激光惯组振动附加角速率比较一致,说明惯组输出角速率系减振系统附加角振动引起。本论文研究的结论对惯性系统减振系统的设计及如何减小惯组角速率输出有一定的参考意义。The causes of torsional vibration and its influence factor of inertial unit under a linear vibration excitation through damper system of a key model of laser inertial unit were described.A method to measure the amplitude and calculate the frequency of torsional vibration and experiment was introduced.The analysis of the test results and comparison with additional angular rate from laser gyroscope indicated that the angular rate derived from two systems were consistent,which show that theinertial output angular rate was caused by damper system torsional vibration.The study had some reference significance to damper system design and additional angular rate reduction.
