摘要
采用锤击法对细长弹性体进行了动态测试,并应用有限元法对细长弹性体的振动进行了理论分析,最后,将实验结果与理论分析相比较,证明了锤击方法的实用性与可靠性。
In this paper. A dynamic test of long-thin elastic boby has been done by hammering
method. The vibration of long-thin elastic body was analysed by finite element method. At
last, compares the results of the test and the theorical analysis. The reliability of the hammer-
ing method was demonstrated.
