摘　　要：结合在Ansys中对起重机起升机构制动器不同制动频次下温度场仿真结果,得出JC值和制动周期T决定了饱和温度大小。在此基础上,对制动频次、制动温升和制动力矩等参数间的关系进行探讨,得出饱和温度是影响制动力矩的主要因素,论证了依据制动频次划分制动器工作级别的合理性,为具体划分提供了理论基础。According to the simulation results of the temperature field tbr the brake of crane httmg mechamsm unoer different braking frequencies, it＇s concluded that the JC value and braking period T determine the saturated tempera- ture. Based on this, the relationship among parameters such as the braking frequency, braking temperature rise, and bra- king torque is analyzed, indicating that the saturated temperature is a major indicator affecting the braking torque. The paper demonstrates that it＇s reasonable to classify the brake based on the braking frequency, providing theoretic basis for the up- plication
