中文摘要:
      加速度驱动阻尼(Acceleration Driven Damper, ADD)控制策略原理简单、易于工程化应用,但其阻尼系数的选择对控制效果有重要的影响。基于理想ADD控制悬架系统模型,分析不同阻尼系数对悬架响应的影响;建立悬架系统综合性能目标函数,仿真得到理想ADD控制策略最优阻尼系数。基于磁流变半主动悬架系统仿真模型,进行ADD控制策略阶跃和随机路面激励仿真。仿真结果表明,在随机激励下,车身加速度可以降低11.83%,但会恶化轮胎动载荷及悬架动挠度指标,使得轮胎动载荷和悬架动挠度分别增加7.98%和15.45%;与被动悬架系统相比,ADD控制磁流变半主动悬架对较高频激振下的车身加速度有较好的抑制作用;同时,ADD控制算法在车身加速度过零时,阻尼力高频切换会引起颤振现象。
英文摘要:
      The principle of Acceleration Driven Damper (ADD) control strategy is simple and easy to be applied in engineering, but the choice of its damping coefficient has an important influence on the effect of control. Based on the ideal ADD control suspension system model, the influence of different damping coefficients on the response of the suspension was analyzed; the overall performance objective function of the suspension system was established, and the optimal damping coefficient of the ideal ADD control strategy was obtained by simulation. Based on the simulation model of the magnetorheological semi-active suspension system, simulation experiments of ADD control strategy step and random road excitation were carried out. The simulation results show that under random excitation, the acceleration of the vehicle body was reduced by 11.83%, however, the tire dynamic load and suspension dynamic deflection index was deteriorated, which increased the tire dynamic load and suspension dynamic deflection by 7.98% and 15.45%, respectively; Compared with the passive suspension system, the ADD-controlled magnetorheological semi-active suspension has a better suppression effect on the body acceleration under higher frequency excitation; meanwhile, when the body acceleration crosses zero, the desired damping force of the ADD control would switch at a high frequency, causing chatter.
