摘要
为提高传统军用轮式车辆橡胶轮胎防穿刺、防爆胎以及环境适应性方面的性能,提出一种主辅弹簧结构车轮。该车轮由金属圆柱螺旋压缩弹簧相互编织、勾连而成。在深入分析了车轮的系统构成与工作原理的基础上,结合主簧接地时的径向受力情况,建立了主簧力学模型并计算了其径向刚度。加工制作了车轮试件并进行了静态加载实验,实验结果与理论计算结果吻合较好,验证了力学模型的正确性和车轮设计的可行性,对车轮结构的优化和改进具有指导意义。
To improve the traditional military wheeled vehicle rubber tire performance of puncture-proof, explosion prevention and environment adaptability, a main-auxiliary spring structure wheel was propesed. The new wheel was composed base on metal helical springs mutual woven and interwined. By analyzing the system structure and working principle and combining with the main spring＇s radial force when it contact ground, the mechanical model was establised and the radial stiffness was calculated. The wheel sample was manufactured and assembled, and the static load experiment was finished. The results was consistent with the theoretical calculations and verified the correctness of mechanical model and feasibility of the wheel design, which has the guiding significance for optimization and improving the wheel structure.
