摘要
为实现对重载轮胎正向特性分析,弥补实验方法费时、费力,且对于复杂、极端工况下轮胎变形信息采集不充分不全面的缺点,开展了基于精细参数化建模的重载轮胎接地特性分析与验证。利用ABAQUS软件,建立了16.00R20型重载子午轮胎精细参数化模型;通过轮胎加载实验和模态测试实验,对模型进行刚度和模态验证;通过重载轮胎加载实验和有限元仿真对比分析研究了不同胎压、不同载荷下的轮胎接地特性。结果表明:上述建模方法建立的模型具有较高的精度,数据对比具有较好一致性;轮胎接地印痕长度随轮荷增大线性增长;轮胎接地印痕宽度随着轮荷的增加缓慢增长到轮胎胎面宽度后不再增大;减小胎压导致接地印痕的长度和宽度显著增大。
In order to achieve the analysis of the forward characteristics of heavy-duty tires and compensate for the shortcomings of time-consuming and labor-intensive experimental methods,as well as insufficient and incomplete collection of tire deformation information under complex and extreme working conditions,a fine parameterized modeling based analysis and verification of the grounding characteristics of heavy-duty tires was carried out.A non-linear finite element model of 16.00R20 heavy-loaded radial tire was established using ABAQUS software.The stiff-ness and modal of the model were verified by tire loading experiment and modal test experiment.The ground contact characteristics of different pressure and load were investigated by means of tire loading test and the finite element sim-ulation.The results show that the model established by above modeling method has high accuracy and good consisten-cy in data comparison;The footprint length increases linearly with increasing wheel load;The width of the tire foot-print slowly increases with the increase of wheel load until it no longer increases after the width of the tire tread;Re-ducing tire pressure results in a significant increase in the length and width of the grounding mark.
