随着机械阻抗测试技术不断发展,机械阻抗法在振动问题中的应用日益广泛。本文简单叙述了机械阻抗法的概念,系统推证了刚性基础下单级和双级隔振的传递率。同时指出,在高频振动隔离下,必须考虑波动效应的影响。为此,应用四点参数技术,从理论上进行推证,给出对应于非刚性设备和基础条件下的传递率表达式。

With the development of mechanical impedance testing technology, the mechanical impedance method is widely used in vibration problems. In this paper, the concept of mechanical impedance method is briefly described, and the transfer rate of single-stage and double-stage vibration isolation based on rigid foundation is deduced systematically. Also pointed out that in the high-frequency vibration isolation, we must consider the impact of fluctuations. To this end, the application of four-point parameter technology, from the theoretical deduction, given under non-rigid equipment and under the conditions of the transfer rate expression.
