Title:
FEEDBACK CONTROL SYSTEM VIBRATION ABSORBING SUSPENSION
Document Type and Number:
Japanese Patent JPS5610844
Kind Code:
A
Abstract:
PURPOSE:To improve vibration absorbing performance by detecting the relative speed between articles including vibration source and the foundation which suspends the article and allowing magnetic flux to be generated according to the detected value and feedback-controlling the vibration absorbing force between the articles and the foundation. CONSTITUTION:When an engine is suspended on a frame, each connection rod 2, 14 is connected with engine side and frame side. When a relative displacement is generated between engine and frame in car travelling, the voltage which is proportional to the relative speed is generated in a coil 12 as sensor mechanism. The voltage is input into a commutation-integrator 33 through an amplifier 31 and a low range filter 32 from the point (b). The output is input into a servo-amplifier 35 through a variable resistor 34, and the differential voltage from the standard voltage is input into an excitation coil 19 through a power amplifier 36, the point (a), and a lead wire 25. As a result, magnetic fluid 17 is properly magnetized, and a proper vibration restricting force acts between a cylinder 1 and a piston 5.
