半主动式减振技术在国内商用车领域的研究与应用

随着全球经济一体化的持续发展,近年来商用车辆工业在中国如火如荼地蓬勃发展。随着国外商用车底盘技术的渗入,国内用户对商用车性能、舒适度的要求与期望早已超越了传统概念中对车辆作为代步工具的要求。减振器,作为商用车悬架中集舒适与安全性能为一身的关键零配件,首当其冲地迎来了一场技术革新。如今商用车工业已经进入了多元化时代,为了迎合客户多层面的要求,减振器如何解决与平衡整车舒适性和操控性这一对矛盾体成为当前底盘技术研发的主要方向。通过对根据频率可调节式阻尼减振器(Frequency Selction Damper,以下称FSD减振器)的研究与应用,从而为商用车底盘悬架的设计、调教提供多元化的选择,改变固有的被动式减振器工作方式以及推广半主动式减振器在国内商用车底盘悬架技术中的发展。

The Application of Frequency Selection Damper Technology in Commercial Vehicle

With the sustainable development of global economic integration of the commercial vehicle manufacture market, automobile in- dustry growth rapidly these years in China. The requirement of the vehicle has been already promoted to the level which is much higher than the ＂tool to replaced foot＂ by people. Especially for the comfortable and safety becomes to the major guide line when people decide to buy a car. The shock absorber, which is the component integrated with the comfort and safety in the suspension, brings the technical innovation. Today the automobile is running into the multi-level era. How to balance the shock absorber＇ s comfort and safety in order to meet customer＇ s requirement comes to the direction indicator of development now. To design and apply the frequency selective damper, so as to provide prop- erly solution in the area of commercial vehicle suspension design. Also it could change the old mode of principle for passive shock absorber to spread the development of Semi-Active shock absorber in the filed of domestic commercial vehicle suspension technology.
