System limiting the transmission of mechanical vibrations by frequential filtering

摘要

The system has a physical connection (6) e.g. electromagnetic connection, for transmitting efforts between parts (2, 4), and a control loop controls frequency of the connection. The loop has a measurement unit (10) for measuring a distance separating the parts. A low pass filter (12) filters variation of the distance and conserves the variation of the distance in a frequency band fixed by the filter. A comparator (14) compares filtered values with a set point. The loop controls the connection such that the connection only transmits the efforts in given frequency band. An independent claim is also included for a method for controlling a wireless connection between parts.
