热损伤是重载货车车轮失效的主要原因之一。分析了30t轴重货车不同轮径的车轮在紧急制动工况下的温度场和热应力场,通过分析比较,得出30t轴重货车车轮直径的建议值。
Thermal damage is one of the major causes of failure of a truck wheel. The temperature field and thermal stress field of 30t axle truck with different wheel diameters under emergency braking condition are analyzed. The recommended values of 30t axle truck wheel diameter are obtained through analysis and comparison.
