【Abstract】 With the improvement of China’s comprehensive national strength,rail railway transportation has become the main mode of transportation in modern China. The bogie is one of the key components of rail transit,an important part of which is the gearbox hanger assembly,playing an important role in carrying and transferring locomotive traction force and braking force. In the locomotive bogie,the rubber elastic element is the main component of the suspension device. Once the fault occurs,it will bring great hidden danger to the locomotive running,and the change of its performance parameters will also affect the train’s running comfort and stability. Herein,the gearbox derrick assembly in the suspension parts of the locomotive bogie was taken as the research object,and SW software was used to establish the gearbox derrick assembly model; the 3-D model structure was simplified,the model parameters were optimized,and the strength of gearbox derrick assembly rod was checked through FEA analysis software. The research contents were as follows:1) Under the working condition of 100 k N ultimate tensile load,the gear box boom structure was analyzed,checking whether the material of 42 CrMo meets the strength requirement; 2) Under the working condition of 100 k N ultimate compression load,the gear box boom structure was analyzed,checking whether the material of 42 CrMo meets the strength requirement.更多还原
