摘要:

The standard approach to vibration isolation analysis represents the source, isolator, and receiver by their mobilities. However, the choice of appropriate descriptor for each element is not arbitrary. Causality arguments show that whether the isolator is treated as a one‐port or a two‐port element, at least one of the system components must be represented by its impedance.
