摘要
潜艇因其隐蔽性能的要求,对噪声振动有着很高的要求。动刚度作为弹性元件隔振能力的主要指标,有必要对其测试方法展开研究。对两种典型的弹性隔振元件的低频动刚度测试方法进行了研究,搭建了动刚度测试试验台,实测了弹簧与橡胶的频率—动刚度曲线,测试结果对弹性元件的使用有着实际参考价值。
Submarine has high requirements on noise and vibration because of its hidden performance. The dynamic stiffness is a main indicator of elastic element. It is necessary to do research on its measure method. In this paper, test method of low-fre- quency dynamic stiffness of two typical elastic elements were studied and test platform for dynamic stiffness was built. The fre- quency-dynamic stiffness curve of spring and rubber was tested and the test result has a factual instructive suggestion for the use of elastic elements.
