根据6×6无人驾驶车辆悬架系统的性能要求,提出独立铰接摆臂悬架系统技术方案,推导出悬架系统中橡胶弹簧扭转刚度的计算公式,并对单个车轮的悬架刚度、偏频进行分析计算。结果表明:随着摆臂角度的增大,悬架刚度逐渐减小;在车辆的摆臂角度大于30°时,悬架偏频n为1~1.6,符合平顺性的基本要求。
According to the performance requirements of the 6 × 6 unmanned vehicle suspension system, the technical proposal of the independent articulated arm suspension system is proposed, and the formula for calculating the torsional stiffness of the rubber spring in the suspension system is deduced. The stiffness, Frequency analysis and calculation. The results show that the suspension stiffness decreases with the increase of the swing arm angle. When the swing angle of the vehicle is greater than 30 °, the suspension bias n is 1 ~ 1.6, which meets the basic requirements of ride comfort.
