为成功设计出一款全地形铰接履带运输车,对其悬挂装置的扭杆弹簧进行研究。由使用材料的剪切强度和疲劳强度确定了扭杆弹簧工作直径,介绍了该车扭杆弹簧端部和过渡段的形式及设计方法,并对已确定的扭杆弹簧的结构尺寸进行整车的动力性能和缓冲性能验证。结果表明:所确定的扭杆弹簧的结构满足材料的强度可靠性和耐久性要求及满足整车动力性能和缓冲性能的要求,并为类似车辆扭杆弹簧的研究提供参考。
In order to successfully design a all-terrain articulated tracked vehicle, the torsion bar spring of its suspension device was studied. The working diameter of the torsion bar spring is determined by the shear strength and the fatigue strength of the used material. The forms and design methods of the ends and transition sections of the torsion bar spring are introduced. The structure of the torsion bar spring Dynamic performance and cushioning performance verification. The results show that the structure of the torsion bar spring can meet the requirements of the strength, reliability and durability of the material and meet the requirements of vehicle dynamic performance and cushioning performance, and provide reference for the research of similar torsion bar spring.
