Structural Design and Analysis of Automotive Hydraulic Damper with Regulating Valve

为了提高汽车行驶过程中平顺性和运行稳定性,设计了一种具有调节阀的液压阻尼器,达到高精度控制与快速响应的功能。该阻尼器中的阀芯在衔铁推动下运动,实现进出油口流量调节,达到阻尼器呈现阻尼特性的效果。研究结果表明:随着电压幅值提高,阀芯触动时间逐渐缩短,改变激励电压并不会造成响应时间变化。随着阀芯移动速度增大,阻尼系数呈线性提高,上升时间逐渐增加。该研究有助于提高汽车液压阻尼器控制精度,为后续的整体性能优化奠定一定的理论基础。

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.
