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。
In order to improve the anti-puncture, explosion-proof tire and environmental adaptability performance of the traditional military wheeled vehicle rubber tire, a main and auxiliary spring structure wheel is proposed. The wheel by the metal cylindrical spiral compression spring weaving, hook made. Based on the analysis of the system structure and working principle of the wheel, the mechanical model of the main spring was established and the radial stiffness was calculated based on the radial force when the main spring was grounded. The wheel specimen was machined and the static loading experiment was carried out. The experimental results are in good agreement with the theoretical calculation results. The correctness of the mechanical model and the feasibility of the wheel design are validated, which is instructive for the optimization and improvement of the wheel structure.
