履带板挂胶对实心轮胎散热影响的有限元分析

采用ANSYS有限元分析软件，在不改变橡胶材料整体厚度的前提下，建立不同挂胶材料和厚度的履带板和实心轮胎的力学场和温度场有限元模型，模拟研究履带板挂胶材料和厚度对实心轮胎散热的影响。结果表明，实心轮胎的最大应力随着履带板挂胶厚度的增大而增大，而最高温度则随着履带板挂胶厚度的增大而降低；在载荷、速度、履带板挂胶厚度相同的情况下，聚氨酯弹性体履带板挂胶比天然橡胶生热少、温升低。;The finite element analysis(FEA) models on the mechanical field and temperature field of track and solid tire rubber with different thickness were established by using ANSYS FEA software under the condition that overall thickness of the rubber was kept unchanged，in order to simulate the effect of material and thickness of track rubber on the heat dissipation of solid tire.The results showed that，when the thickness of track rubber increased，the maximum stress of solid tire increased， but the maximum temperature was reduced.Compared with NR，the heat build-up of the track rubber with PU elastomer was less and the temperature rise was lower under same load，velocity and track rubber thickness
