A semi-active system for control of the energy transmission by means of joint or oscillation between two components located at a distance from one another.

摘要

The system is semi-active and includes a passive isolator and an active damper coupled in parallel between spaced members. The damping characteristics of the damper are actively varied as a function of some control condition such as displacement, velocity, acceleration or the like for generating an actively controllable force resistant to relative movement between the members. The system is particularly useful as a suspension system for reducing the transmissibility of shock and vibratory energy between a mass and support therefor.
