Analysis of Locomotive Axle Load Transfer with Considerationof Adhesive Force Varying for Each Axle

机车电传动, 2014
Considering the distribution of adhesive force varying with the axle load, the arithmetic of axle load transfer should beimproved. Taking a six-axis and a four-axis locomotive as cases respectively, arithmetic with considering and no considering adhesive
