摘要
建立免充气蜂巢式轮胎与地面接触的有限元模型,进行接地性能的相关分析。研究结果表明,与充气轮胎相比,胎面采用聚氨酯弹性体、胎体采用聚甲醛塑性材料的免充气蜂巢式轮胎具有更大的径向刚度和横向刚度,表明在降低滚动阻力和增强操控稳定性方面有优势,但是其胎面中心区域的接触应力最大,造成该区域磨损较为严重。
The finite element model of honeycomb non-pneumatic tire contacting with ground was established to analyze the contact performance. The results indicated that, compared with pneumatic tire,the honeycomb non-pneumatic tire made of polyurethane elastomer for tread and polyformaldehyde plastic materials for carcass possessed higher radial stiffness and lateral stiffness, indicating lower roiling resistance and better driving stability. But the maximum contact force was at the central part of the tread for honeycomb non-pneumatic tire, resulting in serious wear of that part.
