计及外流场的子午线轮胎温度场建模方法
Analysing Temperature Field of Radial Tire with External Flow Field

为了准确模拟轮胎使用过程中温度场分布情况，提出了一种计及外流场的子午线轮胎温度场建模方法。以某205/55R16型轿车子午线轮胎为研究对象，使用ABAQUS以及ANSYS软件建立轮胎自由滚动力学模型以及轮胎温度场模型，并通过轮胎测温试验验证了仿真模型的可靠性。以热对流、热辐射、热传导3个方面考虑轮胎温度场分布，同时考虑了轮胎实际运行中外部流场的影响。结果表明，新的轮胎温度场建模方法能够更加合理准确的模拟轮胎内部以及外部的温度场与流场分布，对于轮胎性能研究有着十分重要的意义。
In order to improve the accuracy of a radial tire's temperature field analysis, we propose a new modelling method with the external flow field considered. To study the PCR tire 205/55R16, the finite element model of the radial tire and its stable temperature field is established by using the ABAQUS and ANSYS software. The thermal parameters and the mechanical parameters of the radial tire's materials are tested with the RPA2000 instrument and the hot-disk instrument. The mechanical model of the tire is simulated with the ABAQUS software, and the flow field analysis is simulated with the ANSYS software. The convection, heat radiation, heat conduction of the radial tire are analysed with the ABAQUS software. The temperature of the radial tire is experimentally tested to prove that the simulation model is reliable. The test results show that compared with the existing methods, the new radial tire temperature field simulation method, which is helpful to study the performance of a radial tire is more accurate and reliable
