| Abstract: |
| In this paper, the load characteristics and the test conditions of the environment for the flighting missiles are analyzed, and the shortcomings of the traditional test methods in some cases are pointed out. The vibro-acoustic environment test method and the flexible suspension-multi exciter vibration test method are introduced briefly. Also their virtues and shortcomings are analyzed. The vibro-acoustic environment test method can reproduce the broadband vibro-acoustic environment more accurately, and the multi-exciter vibration test method is more suitably to simulate the surface distributed load in flight. The flexible suspension method can simulate the free boundary conditions. All these test methods can be the complementarity of the conventional test methods. And the rational apply of these methods can reproduce the environment of the flighting missiles more accurately. |
