摘要: 为保证电动滑板车悬架的承载和减震性能，定义预载力、轮轴中心位移、整件刚度3个设计目标，通过仿真与试验对比验证对橡胶衬套使用连续工况非线性大变形仿真方法的有效性，据此设计橡胶衬套元件原始方案并进行仿真计算，确定可能的优化方向，经过多次优化设计和仿真，最终获得满足设计目标的优化方案。样件试验结果验证仿真及优化设计的有效性。Abstract: To ensure the load-bearing and shock absorption performance of the electric scooter suspension, three design objectives are defined:preload force, axle center displacement, and overall stiffness. The effectiveness of the continuous working condition nonlinear large deformation simulation method for rubber bushings is verified by simulation and experimental comparison. Based on this, the original scheme of rubber bushing components is designed and simulated to determine possible optimization directions. After multiple optimization designs and simulations, the optimization scheme that meets the design objectives is finally obtained. The results of the sample test validate the effectiveness of the simulation and optimization design.
