The invention belongs to the technical field of suspension vibration reduction, and particularly relates to a suspension system rigidity adjusting method, which is characterized in that the adjustment of rigidity characteristics is mainly reflected in two aspects of static adjustment and dynamic adjustment during advancing, in the static adjustment aspect, firstly, the internal working pressure of hydro-pneumatic suspension is collected through a sensor, and the wheel load state is calculated; the hydraulic control pneumatic system is used for charging and discharging the air quantity of the suspension energy accumulator, the offset frequency of the vehicle body is adjusted to a reasonable range, after the air quantity is adjusted, a control algorithm needs to be formulated to drive the vehicle posture adjusting hydraulic valve set to charge and discharge the oil quantity of the suspension oil cylinder, the distance between the vehicle bottom and the ground at a target position is achieved, and the traveling requirement is met. In the aspect of dynamic adjustment of rigidity characteristics during advancing, a stroke variable rigidity control method and an acceleration variable rigidity control method are provided.
本发明属于悬挂减振技术领域,具体涉及一种悬挂系统刚度调节方法,其为对刚度特性的调整主要体现在静态调整和行进间动态调整两个方面,在静态调整方面,首先通过传感器采集油气悬挂的内部工作压力,计算轮荷状态,并通过液控气动系统对悬挂蓄能器进行气量的充放,将车体偏频调整到合理范围,在气量调整完成后,需要制定控制算法驱动车姿调节液压阀组对悬挂油缸进行油量的充放动作,达到目标位的车底距地高,满足行车要求。在刚度特性的行进间动态调整方面,提出行程变刚度的控制方法和加速度变刚度的控制方法。
