摘　　要：为准确模拟滚动实心轮胎温度场分布情况,提出一种滚动轮胎黏弹性力场的模拟方法,用以精确计算胶料生热率.以目标假车轮胎为研究对象,考虑Mullins效应对橡胶黏弹性力学行为的影响,选用Mooney-Rivlin模型进行滚动轮胎黏弹性力场模拟.采用傅里叶级数拟合周期应力、应变的方法计算胶料生热率,对滚动轮胎温度场进行模拟,并通过轮胎测温试验验证仿真方法的有效性.结果表明,通过模拟滚动轮胎黏弹性力场可精确计算胶料生热率,能够更合理、准确地模拟轮胎稳态温度场.基于此仿真方法研究最高温度与轮胎结构及材料的关系,通过改变工艺、优化橡胶材料及轮胎结构来提高轮胎的耐温极限.To accurately simulate the temperature field distribution of rolling solid tires,a simulation method of viscoelastic force field of rolling tire was proposed to accurately calculate the heat generation rate of rubber compound.To study the tire of target car,the influence of Mullins effect on the viscoelastic behavior of rubber was considered,and the Mooney-Rivlin model was used to simulate the viscoelastic field of rolling tire.The heat generation rate was accurately calculated by the Fourier coefficient to simulate the temperature field of the rolling tire,and the temperature of the tire was experimentally tested to verify the simulation method.The test results show that the calculation of the heat generation rate by the viscoelastic field of rolling tire can simulate the steady temperature field of tire more reasonably and accurately.Based on the proposed simulation method,the relationship between the highest temperature and the structure and material of tire can be investigated,and the temperature resistance limit of the tire can be improved by changing the process,the rubber material and the tire structure.
