    摘要:

    在建立整車磁流變減振器(MRD)半主動懸架模型基礎(chǔ)上,利用八板塊方法設(shè)計了整車的變論域控制策略?;谥貥?gòu)的標準B級和C級路面激勵信號,分別在10、20和30m/s 3個車速下進行了整車在直線和轉(zhuǎn)向行駛工況下的仿真研究。在完成試驗車輛改裝基礎(chǔ)上,進行了大量臺架和道路工況下的試驗。仿真和試驗結(jié)果顯示,所設(shè)計的半主動懸架和控制策略可以有效地提高車輛行駛的平順性,磁流變半主動懸架與被動懸架相比振動強度可降低9%~22%,結(jié)果表明所建立的模型和控制策略是可行的。

    Abstract:

    The variable universe control strategy was adopted from the octa-plate control method for whole vehicle MRD semi-active suspension model. Simulations of vehicle travelling both straight and turning with the speed of 10 m/s, 20m/s and 30m/s were done in reconstruction standards B and C level road excitation signal. Large numbers of bench tests and road test have been done upon the completion of the modification of the vehicle. Simulation results showed that the designed semi-active suspension and control strategy had effectively improved the smoothness of the ride and there was 9% to 22% reduction in vibration intensity of the magneto rheological semi-active suspension and the passive suspension. The results showed that the model and the control strategy were feasible. 
