Improving shunting-export locomotive towline when operating in strip mine based on its stationary thermal model

[摘要] There is the technique of improving shunting-export rolling stock towline when operating in a strip mine on the basis of its stationary thermal model founded on calculating the thermal resistances and permitting to determine the temperature of the most thermally loaded node. The technique was tested for the model of the engine AO-63-4 and shunting-export locomotive TEM7. There is the method of calculating thermal resistances of separate units on the basis of design features and the geometrical sizes of the asynchronous motor. It is concluded that the rods of the engine rotor AO-63-4 are most intensively heated.
