In order to solve the existing problems of domestic applications, an innovative structure design for the draft gears of locomotive couplers is developed using the mechanical principles and the finite element method. In the condition of ensuring the performance, the draft gear structure is optimized, the number of draft gear parts is reduced, and the weight and cost of draft gear are cut down. After absorbing the foreign technologies, a new locomotive coupler draft gear is developed which achieves the equivalent-level performances as those of developed countries and fills the domestic gap. |
