| Abstract: | 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. |
