弹性元件动刚度的直接法实验研究

Direct Method Experiment Research on Dynamic Stiffness of Resilient Element

针对现有居民变电站变压器重心过高,导致出现明显的摇摆现象,引发的结构噪声较大的问题,提出了建立新型"Z"型隔振器方案,以解决变压器重心过高所引起的摇摆问题。针对变压器的优势频率选择弹簧,并通过弹性元件振动-声传递特性实验室测量方法的直接法测量原理,搭建实验平台,测试隔振器弹簧的动刚度,分析得出弹簧的动态性能,以满足隔振器设计要求。

This paper mainly concentrated on the high center of gravity of the transformer substation that leads to the swing phenomenon and the construction noise. And on the basis we designed the ＂Z＂ type iso- lator to solve the problem. And we choose the spring basis on the dominant frequency of the transformer and set up the experimental platform and test the dynamic stiffness of the spring according to the laboratory measurement of vibro-acoustic transfer properties of resilient elements, and analyzed the dynamic property of the spring to meets the design requirements.
