以某减振器为研究对象,通过建立三维内流场模型,运用计算流体力学的方法仿真计算减振器的内流场分布情况,仿真结果与实验结果一致性较好,表明所建立的三维内流场模型真实可靠。运用该仿真模型计算分析减振器常通孔尺寸、节流阀最大开度、节流阀内径、活塞杆直径、气体的种类、充气量以及气体的压强等因素对减振器动态性能的影响情况,可以为实际工程中减振器的设计开发提供一定的参考依据。
Taking a shock absorber as the research object, the three-dimensional internal flow field model is established and the flow field distribution of the shock absorber is simulated by computational fluid dynamics. The simulation results are in good agreement with the experimental results, indicating that the established three-dimensional The internal flow field model is reliable. The simulation model is used to analyze the influence of the size of the through hole, the maximum opening of the throttle valve, the diameter of the throttle valve, the diameter of the piston rod, the type of gas, the inflating capacity and the pressure of the gas on the dynamic performance of the shock absorber The situation can provide some reference for the design and development of the shock absorber in the actual project.
