摘要: 为了提升含减振元件惯容器的车辆悬架系统的综合减振性能,建立了含有减振元件惯容器、弹簧、阻尼器的车辆悬架系统模型.采用遗传算法对悬架参数进行优化,基于振动功率流理论对减振元件衬套进行优化选型.通过对车辆悬架系统动力学模型进行数值求解,探究了参数优化前后车辆悬架系统的动力学响应,探讨了衬套参数对功率传递的影响.研究结果表明,相比原始设计参数,采用优化算法得到的参数能够有效改善车辆悬架系统的综合减振性能,理论计算与仿真数据的结果相互验证了所建模型的正确性,衬套的优化选型有助于进一步提高车辆悬架系统的减振性能.

Abstract: To improve the comprehensive damping performance of vehicle suspension system with inerter, the system with inerter, spring and damper was modeled. Genetic algorithm was used to optimize the suspension parameters, and the theory of vibration power flow was used to optimize the selection of the damping element bushing. Based on the numerical solution of the model, we discussed the dynamic response of the system before and after the parameter optimization and the influence of the bushing parameters on the power transmission. The research results show that, the parameters obtained by the optimization algorithm can effectively improve the comprehensive damping performance of the system, as compared with the design parameters. The theoretical calculation and simulation data mutually verify the correctness of the model. The optimized selection of the bushing is helpful to further improve the damping performance of the vehicle suspension system.

Key words: vehicle damping, vehicle suspension, inerter, parameter optimization, power flow, dynamics
