摘要
基于聚氨酯弹性体优异的性能,建立了3种不同密度的蜂巢式塑料轮胎模型,并以ABAQUS软件为工具,以同型号的传统橡胶轮胎为参照,对比分析了稳态滚动工况下轮胎的接地性能和应力分布。分析结果表明,与传统橡胶轮胎相比,蜂巢式塑料轮胎的等效应力分布更加均匀。因此,蜂巢式塑料轮胎局部发生过度磨损的可能性降低。此外,蜂巢式塑料轮胎支撑板的受力情况与蜂巢密度密切相关。
Based on superior performance of polyurethane elastomer,three different density of honeycomb plastic tires models were established,the same model of the traditional rubber tires were taken as reference,and ABAQUS software was used as analysis tool to compare and analyze the grounding performance and stress distribution of the plastic tires under the steady rolling conditions. The results show that the equivalent stresses of honeycomb plastic tires distribute more uniformly than that of the traditional rubber tires. Therefore, the possibility of excessive wear of honeycomb plastic tires gets smaller. In addition, the stress conditions of support plates of the tires are closely related to honeycomb density.
