基于ADAMS/Car建立了某微型轿车的4种不同结构的柔性拖曳臂后悬架模型,以及整车刚柔耦合虚拟样机模型进行了稳态回转道路试验,通过试验与仿真结果的对比,验证了整车模型的正确性。对不同结构的后悬架并进行运动学仿真,研究拖曳臂式后悬架结构改变对整车稳态回转性能的影响。对装有4种拖曳臂悬架的整车模型进行稳态回转仿真,结果表明:通过拖曳臂悬架的加强筋长度,来减小后悬架的侧倾角刚度,可以有效的改善整车稳态回转性能。
Based on ADAMS / Car, four kinds of flexible trailing arm rear suspension model of a miniature car and a rigid-flexible coupled virtual prototype model of a miniature car were established for steady-state rotary road test. The comparison between the simulation results and the test results shows that The correctness of the vehicle model. The kinematic simulation of the rear suspension with different structures is carried out to study the influence of the structural changes of trailing arm rear suspension on the steady-state slewing performance of the vehicle. The steady-state simulation of the vehicle model with four kinds of trailing arm suspensions is carried out. The results show that the stiffness of the rear suspension can be reduced by dragging the stiffener length of the arm suspension, which can effectively improve the vehicle stability State rotation performance.
