| 摘 要： | 在考虑道路条件和车辆运行状况的前提下,研究了汽车鼓式制动器的摩擦生热过程、辐射换热过程和对流换热过程,建立了其温升计算的数学模型。在相似理论和量纲分析理论的指导下,进行鼓式制动器对流换热试验,得出了鼓式制动器对流换热的求解公式。试验验证结果表明,采用所建模型计算得到的温升曲线与试验测得的曲线变化趋势基本相同,最大误差约为20%。

| Abstract: | In the condition of considering road and automotive operation status,research the process of friction heat generation,radiation heat exchange and convection current heat exchange,and establish mathematic model of temperature rise calculation.Under the guidance of similarity theory and dimension analysis theory,do the test of convection current heat exchange of drum brake,and get the solution equation of convection current heat exchange of drum brake.The results show that the temperature rise curves between calculation and test are basically identical,the maximum inaccuracy is approximately 20 %. |
