摘要
为了研究某型筒弹在运输激励下的振动响应情况,给筒弹设计提供参考,利用时域频域转换方法和有限元理论,提出一种间隙非线性筒弹随机振动计算方法。通过仿真计算,研究筒弹在车辆运输振动环境下的响应问题,并与试验进行对比,为筒弹运输振动研究及筒弹设计提供一种新的方法。
In order to study the vibration response of missile-in-container under transportation excitation and provide reference for the design of missile-in-container,a freeplay nonlinearity random vibration calculation method of missile-in-container is proposed in this paper by using time-frequency domain conversion method and finite element theory.Response of missile-in-container under vehicle transportation vibration environment is obtained by simulation calculation,and is compared with the experiment,which provides a new method for the research of transportation vibration and the design of missile-in-container.
