Structural Design and Analysis of Automotive Hydraulic Damper with Regulating Valve
In order to improve the smoothness and operational stability of the automobile during driving,a hydraulic damper with a regulating valve is designed to achieve the functions of high-precision control and fast response.The spool in this damper moves under the push of armature to realize the inlet and outlet flow adjustment to achieve the effect of damper presenting damping characteristics.The research results show that:with the increase of voltage amplitude,the spool touching time is gradually shortened,and changing the excitation voltage does not cause the response time to change.As the spool moving speed increases,the damping coefficient shows a linear increase,and the rise time gradually increases.This study helps to improve the control accuracy of the automotive hydraulic damper and lays a certain theoretical foundation for the subsequent optimization of the overall performance.
