【摘要】 研究聚氨酯实心轮胎的内生热特性。结果表明 ,以PTMG为软段、TDI MOCA为硬段、邵尔A型硬度为 80～ 90度之间的聚氨酯弹性体模型负重轮具有良好的耐热性能。轮胎的温升随载荷和转速的增大而升高。环境温度对轮胎的温升有一定影响更多还原

【Abstract】 The interior heat build-up in PU solid tire was investigated.The results showed that the tire model of PU with 80～90° Shore A hardness and using PTMG as soft segment and TDI-MOCA as hard segment respectively featured good heat resistance;the temperature rising of tire increased as the tester speed increased;and the environment temperature had some influence on the temperature rising of tire.更多还原
