摘　　要：基于伺服电磁阀的传统节流口面积可调式阻尼减振器存在结构复杂、设计精度要求高以及控制难度较大等缺点,针对这一问题,提出了一种基于开关电磁阀的新型阻尼可调减振器。完成了该阻尼可调减振器的结构设计,分析了其实现不同阻尼状态的工作原理;在此基础上,进一步阐述了阻尼可调减振器阻尼特性模型的构建流程;最后,通过仿真分析了减振器主要结构参数对其阻尼特性的影响规律。研究结果表明:所设计的减振器通过改变2个电磁阀的通断状态,即可实现4种阻尼模式、8种阻尼状态,具有结构简单、可靠性高的特点;同时,阻尼调节装置中的4个单向阀和2个开关电磁阀的相关结构参数对减振器的阻尼特性影响明显;相关结论为可调阻尼减振器特性的分析及主要结构参数的确定奠定一定的理论基础。Aiming at that the traditional shock absorbers with adjustable throttle area are always designed based on servo solenoid valve,which shows many problems,such as complex structure,high design precision requirement and difficult to be controlled,a new type of damping adjustable shock absorber based on on-off solenoid valves was proposed.In the first,the structural design of the target shock absorber was conducted,and its working principle for achieving different damping states was analyzed.On this basis,the establishment process of the damping characteristics model of the target shock absorber was given,and the influence of main structural parameters on damping characteristics of the shock absorber was analyzed by simulations.The results indicate that the designed shock absorber can achieve four damping modes and eight damping states by just changing the on-off statuses of two solenoid valves,which makes it have simple structure and high reliability.Meanwhile,the simulation results shown that the parameters of the four check valves and two on-off solenoid valves have significant influences on the damping characteristics of the shock absorber.The research results will lay an important theoretical foundation for the characteristics analysis and the determination of the main structural parameters of the target shock absorber.
