Demonstrating an Active Vibration Isolation System

摘要

Active vibration isolation (AVVI) systems are becoming more available in various markets, one such market being vehicle operator seating. Unfamiliarity with the performance of such systems may cause users initial perceptions of system performance to be unfavorable. AVI systems can include a demonstration system capable of providing simulations too users of various types of vibration isolation systems under various input conditions, so that users can be introduced to the system benefits over other systems before using an AVI equipped product in its intended application.

主权项

1. A method for demonstrating an active vibration isolation system configured and arranged to isolate a suspended plant from a vibration disturbance comprising:
a first outputting by the active vibration isolation system actuator of a first time domain force to the suspended plant to cause motion of the suspended plant that simulates motion the plant would experience if a predetermined vibration disturbance was applied and the plant was suspended with a passive suspension comprising a spring and damper; a second outputting by the active vibration isolation system actuator of a second time domain force to the suspended plant to cause motion of the suspended plant that simulates motion the plant would experience if the same predetermined vibration disturbance was applied and the plant was suspended with a normally functioning active vibration isolation system; wherein the first and second outputting can occur in any order.
