摘　　要：为了验证控制驱动器在复杂振动环境下的适应性及内部结构的振动放大情况,以一种控制驱动器为研究对象,基于随机振动理论,对其进行振动仿真分析,得到结构响应和应力结果。通过修正优化仿真分析参数,减小仿真结果与随机振动试验结果的偏差,得到更准确可靠的仿真分析方法,从而对控制驱动器的抗振动设计提供理论指导作用。In the field of aerospace servo system,the control driver is an important electronic device.In order to verify the adaptability of the control driver in a complex vibration environment and the vibration amplification of the internal structure,a research based on a control driver is carried out.A vibration simulation analysis is performed to obtain structural response and stress results,by optimizing the simulation analysis parameters,the deviation between the simulation results and the random vibration test results is reduced,and a more accurate and reliable simulation analysis method is obtained,thereby providing theoretical guidance for the anti-vibration design of the control drive.
