摘　　要：为研究开发一种新型越野车用阻尼可调液压减震器的阻尼力调节机构,从已有专利的技术细节出发,分析了阻尼可调液压减震器阻尼力调节机构的布置形式。归纳了阻尼力调节机构的工作原理,根据阻尼调节机构布置形式及调节原理的差别,对调节机构进行了分类;例举了不同类型调节机构的典型结构,并开展了分析,从调节机构的结构层面出发,结合减震器的生产制造过程及使用环境,对比分析了不同类型调节机构的实用性、可靠性、经济性等性能。研究结果表明:杆型调节机构适用于安装空间小、阻尼力值较小、对可靠性及成本要求较低的场景,筒型调节机构适用于安装空间充裕、阻尼力值较大、对可靠性要求较高的场景。Aiming at developing a new model of damping force adjusting mechanism of a damping force adjustable hydraulic shock absorber, the arrangement forms of the adjusting mechanism were analyzed,and the operating principles were summarized according to the technical details of the existing patents.The adjusting mechanisms were sorted into several kinds basing on the distinctions of the operating principles and arrangement forms in different patents,typical structures of different adjusting mechanisms were exemplified and analyzed.Basing on the structure of the regulating mechanism,combining with the manufacturing process and using environment,the practicability,reliability and economic performance of different types of regulators were compared and analyzed.The results indicate that the rod-type adjusting mechanism is suitable for the situation of small installation space,low damping force value with reasonable reliability and cost while the tube-type adjusting mechanism is appropriate for the scene where the installation space is abundant,the damping force value is large,and the demand of reliability is higher.
