摘要 设计了一种阻尼可调的外置阻尼阀,分析了其工作原理、内部结构和阀元件性能.根据流体连续性方程、运动微分方程以及伯努利方程等,从理论上研究了该阻尼阀的阻尼特性,通过仿真分析了其结构参数对阻尼特性的影响.建立了外置可调阻尼阀数学模型,并通过台架实验对数学模型进行了验证.实验结果表明,所设计的外置可调阻尼阀可实现油气悬架阻尼力的三级调节,能够满足车辆悬架系统动态特性的需求;台架实验结果与仿真结果吻合良好,该数学模型能够正确反映阻尼阀的特性. A new outside adjustable damper is developed.The characteristic of the outside damper can be controlled by operating on the adjustable valve.The working principle,elements construction and valve behaviors of the developed valve are studied.The damping characteristics is studied depending on the continuity equation,and differential equations of motion,as well as Bernoulli equation and others.The valve parameters' influence on the damping characteristic is studied by simulation.A new numerical model of the outside adjustable damper is built up.The results of both simulation and test on the bench are compared.The result shows that the developed outside adjustable damper can be adjusted on three stages.It can meet the requirement of the dynamic characteristic of the vehicle suspension system.Also,the simulation results tallies well with the test results on the bench,it indicates that the new numerical model is suitable for the developed damper.
