【摘要】 利用电模拟惯量转矩控制模型,在制动力矩-电模拟惯量二元函数关系基础上,分析了电模拟惯量的大小范围与制动力矩、电机转矩的关系,并探讨了制动力矩及电机输出转矩对正、负惯量的模拟范围的影响.提出了针对实际的列车制动过程的转速-制动力矩-电模拟惯量三元关系,根据实际试验台参数进行计算,得到三维电惯量模拟范围,从而实现了列车制动试验台惯量模拟范围的确定.由三维电惯量模拟范围可知,在不同的制动力矩及转速条件下,列车制动试验台电惯量模拟范围不同,并且存在惯量模拟的极小值点.三维电惯量模拟范围对于评价制动试验台模拟实际列车载荷的能力具有重要意义.更多还原

【Abstract】 Using the electric analog inertia torque control model, the relationship between the size range of the electrical analog inertia and the braking torque and the motor torque is analyzed on the basis of the two-element function relationship of the braking torque and electric inertia, and the influence of braking torque and motor output torque on the model range of positive and negative inertia is also discussed. The three-element relationship of speed braking torque and electrical analog inertia is proposed for the actual train braking process. According to the parameters of the actual test bench, three-dimensional electrical simulation inertia range is obtained, and the determination of the inertia simulation range of the train brake test rig is realized. The simulation range of three-dimensional electrical inertia is of great significance for evaluating the simulation ability of the braking test rig to actual train load.更多还原
