用于微振动控制的隔振器分析和实验

摘要

The expression of the optimal frequency response of an isolation system was obtained through the analysis of its frequency response function. Based on the result, an isolator for micro-vibration control was designed and its perfor-mance was tested. Vibration acceleration and minimum transmissibility rate of the isolation system with different mass com-ponents and the isolator were measured. The test results were in a good accordance with those of calculation, which indicate that the design of the isolator is correct and effective.%首先从隔振系统频响函数出发，得到系统最优频响表达式，然后根据最优频响条件，设计了一种用于微振动控制的隔振器，并通过实验测试隔振器的特性，获得了由隔振器和不同质量元件构成的系统的振动加速度和振动传递率。实验与理论计算结果一致性较好，说明设计是正确的。
