摘要
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。
The solutions of independent articulated swing arm suspension system was put forward according to the basic the performance requirements of suspension system of the 6 × 6 unmanned vehicle in this paper. The calculation formula of torsion stiffness of rubber spring was deduced. A single wheel suspension stiffness and natural frequency of suspension system were calculated. The results show that suspension stiffness decreases with the increase of the angle of the swing arm. And the suspension system can meet the demands of ride comfort due to natural frequency of suspension system in the range from 1 to 1.6 when the angle of the swing arm is more than 30 degrees.
