摘　　要：基于一种闭环控制方法,对导弹多点激励振动试验系统进行动力学仿真。通过对整个系统进行合理简化,利用MSC.Patran/Nastran有限元软件对振动试验系统进行模态分析及随机振动分析。最后,计算出各控制点的振动加速度响应谱。结果表明,试验结果与仿真结果基本一致,验证了计算机动力学仿真的正确性。Based on a closed loop control method,the dynamic simulation of a vibration test system for multipointexcitation of missiles is carried out.Through the reasonable simplification of the whole system,the modal analysis andrandom vibration analysis of the vibration test system are carried out by using the MSC.Patran/Nastran finite elementsoftware.Finally,the response spectrum of the vibration acceleration of each control point is calculated.The results showthat the test results are consistent with the simulation results,which verifies the correctness of the computer dynamicsimulation.
