| Abstract: |
| The multi-exciter vibration test method is suitable for the vibration loading of large and slender structures. The position of the control points are usually located near the excitation points and the control condition is a ladder spectrum obtained by the envelope method. This method may lead to an obvious difference between the response of test and the real response. Aiming at a short conical structure, this paper proposes a new experimental design method to control different responses of two points in the test structure. The acceleration power spectrum density of two points in the structure is obtained by numerical simulation. A two points excitation is used to control the two points response by using the excitation bar and the excitation plate. The test results show that the responses of the control points have reasonable correlation and the excitation position is reasonable. Therefore, the control effect is very well when the two points response control is carried out. |
