【摘要】：针对5元件ISD悬架元件多、结构复杂、布置困难等问题,设计了一种3元件ISD悬架,研制了其惯容与阻尼串联式液力惯容器装置,并将该装置安装于某型军用越野车的前、后悬架上。偏频试验结果表明,与传统悬架相比,ISD悬架前、后车身偏频分别降低了23.3%和12.5%,且相应偏频处的功率谱密度峰值分别减小了45%和50%。平顺性试验结果表明,ISD悬架能有效抑制车身的垂向、俯仰与侧倾振动,明显提高了汽车的行驶平顺性。3元件ISD悬架元件少、结构简单、易于实现,为ISD悬架的产业化奠定了技术基础。
[Abstract]:Aiming at the problems of ISD suspension with five elements, such as many components, complex structure and difficult arrangement, a three-element ISD suspension is designed, and the series type hydraulic inertial container device with inertial capacity and damping is developed, and the device is installed in front of a military off-road vehicle. On the rear suspension. The results of frequency bias test show that in front of ISD suspension, the bias frequency of rear body is reduced by 23.3% and 12.5%, respectively, and the peak value of power spectral density at the corresponding frequency offset decreases by 45% and 50%, respectively. The results of ride comfort test show that ISD suspension can effectively suppress the vertical, pitch and roll vibration of the vehicle body, and obviously improve the driving comfort of the vehicle with less ISD suspension elements, simple structure and easy realization. It lays a technical foundation for the industrialization of ISD suspension.
