根据某型井下胶轮车油气悬架系统的结构特点和工作原理,阐述其在减振和调节车高两方面存在的问题和不足,提出新的油气悬架系统方案。详细分析新方案的工作原理,采用多体系统动力学的方法,在ADAMS中建立胶轮车油气悬架系统二自由度动力学振动模型,通过仿真分析,表明新油气悬架系统能够有效发挥阻尼阀的作用,对胶轮车振动的衰减更为显著,有利于改善胶轮车的行驶平顺性。
According to the structural characteristics and working principle of the oil-gas suspension system of a downhole rubber tire vehicle, the problems and shortcomings in the aspects of damping and adjusting the vehicle height are expounded. A new scheme of the oil-gas suspension system is proposed. The working principle of the new scheme is analyzed in detail. By using the method of multi-body system dynamics, a two-degree-of-freedom dynamic vibration model of the rubber-tympanic suspension system is established in ADAMS. The simulation shows that the new oil-gas suspension system can effectively dampen The role of the valve, rubber tire truck vibration attenuation is more significant, help to improve the ride rubber tire ride.
