摘　　要：针对某轻型火箭炮发射底盘的低频异常振动问题,采用理论推导、仿真分析和试验验证相结合的方法,进行了轻型火箭炮发射底盘异常振动测试,构建了包括电机悬置参数在内的火箭炮发射底盘振动理论模型和有限元仿真模型,分析了火箭炮发射底盘电机悬置的隔振效果,结合试验结果和理论计算结果,完成了电机悬置的优化设计,并通过电机悬置优化前后的轻型火箭炮发射底盘在炮弹装载过程中的振动试验对比,验证了电机悬置优化的减振效果。试验结果表明:采用电机悬置优化方案后,载运装置的振动情况得到明显改善,装载导轨处的振动功率谱密度峰值由原来的0.67 m/s^(2)下降到0.33 m/s^(2),比优化前降低了50.7%,有效地改善了轻型火箭炮发射底盘的低频异常振动现象。In order to solve the problem of abnormal low frequency vibration of light rocket launcher chassis,this paper combines theoretical derivation,simulated analysis and experimental verification to measure the abnormal vibration of light rocket launchers.A vibration theoretical model and finite element simulation model of rocket launcher chassis including motor mounting parameters is established.And the vibration isolation effect of the rocket launcher chassis motor mount is analyzed.Based on experimental and theoretical calculation results,the design of the motor suspension is optimized.Through the comparison of vibration sustained by the rocket launcher chassis during loading before and after the mounting optimization,the vibration reduction effect of the motor mount optimization is verified.The experiment result shows that after using the optimal design of the motor suspension,vibration sustained by the chassis has obviously improved with the peak value of vibration power spectral density of the loading guide rails reduced from 0.67 m/s^(2)to 0.33 m/s^(2),50.7%lower than before the optimization,which effectively improves the abnormal low frequency vibration phenomenon of light rocket launcher chassis.
