| 摘 要： | 本文探讨了作为模态试验方法之一的多点激振技术。针对某些实验仪器存在的相位移动问题,提出了一种新的多点激振调力方案,并建议了一种识别纯模态下各模态参数的实用方法。经过计算和实验的考核,说明本文方法对于一般结构进行多点激振试验都是适用的。

| Abstract: | A new technique of multi-point exciting for modal testing is discussed. In consideration of the trouble of phase shift in some experimental instruments, a new scheme is proposed to assign multi-point exciting forces and a practical method is provided to discern the modal parameters in pure modes. Calculations and experiments demonstrate that the new technique is applicable to the multi-point exciting experiments for general structures. |
