机动发射系统垂直瞄准扰动试验分析

The interference of vertical aiming of mobile launch system test analysis

针对机动发射竖直瞄准干扰消除问题,设计两种动特性试验获取其扰动频率及幅值;采用传统模态试验方法获取其小变形动态特性,通过释放和风激励方法获取了其晃动动态特性,分析指出非线性间隙对结构动特性影响明显。

Aiming at the problem of anti-interference about vertical aiming during mobile launch,two dynamic character tests were designed to get the frequency and amplitude of interference.Dynamic character of small deformation was achieved through traditional mode-test,and the dynamic character of sway was achieved through release and wind-excitation test.The conclusion was achieved that the structure dynamic character was affected deeply by nonlinear clearance.
