| 摘 要： | 在动力机器基础测试中,拉伸回弹法是一种简易实用的瞬态激振方法;它比常用的球击法具有激振能量大,信号接收效果佳等优点。但运用该法如何求地基刚度的计算却不多见,故本文简要地列出我们推导的算式,以供参考与探讨。

| Abstract: | In the dynamic machinery foundation test, the stretch-elasticity method is a simple and practical transient exciting method. It has some advantages of larger exciting energy and higher efficiency in receiving signals over the conventional ball-shooting method. But no calculation has ever been given to find the foundation rigidity by this method, and therefore this paper presents our way of calculation for reference and discussion. |
