利用ADAMS软件建立3303B型非公路矿用自卸卡车油气悬挂缸的虚拟样机 ,进行仿真研究 ,结合实验测得的数据进行比较分析 ,结果表明仿真研究结果与试验研究结果吻合较好 ,也充分证明了在工程车辆油气悬挂系统的研究中 ,利用ADAMS软件建立仿真模型的可行性 ,对进一步研究油气悬挂缸具有指导性作用 The virtual prototype of 3303B off-highway truck dumper truck was established by using ADAMS software, and the simulation analysis was carried out. The results of the simulation and experimental data show that the simulation results are in good agreement with the experimental results, In the research of the oil-gas suspension system of engineering vehicles, the feasibility of using ADAMS software to establish the simulation model is instructive to the further study of the oil-gas suspension cylinder
