高速动车齿轮箱的悬挂结构是驱动装置的重要承载部件，其不但能承受齿轮传递转矩时箱体的反作用力，还能承受动车高速运行时各方向的振动冲击；因此，在设计时应保证结构具有足够的强度，并且满足结构的减重要求。本文根据齿轮箱承载方式及相关接口尺寸，利用三维设计软件及有限元分析软件，对悬挂结构进行多次优化与强度计算。结果表明，最终设计结构较初始设计结构强度提高了23%，质量减小了12%。对实际结构进行了应力测试，计算结果与测试结果吻合较好。
高速動車齒輪箱的懸掛結構是驅動裝置的重要承載部件，其不但能承受齒輪傳遞轉矩時箱體的反作用力，還能承受動車高速運行時各方嚮的振動遲擊；因此，在設計時應保證結構具有足夠的彊度，併且滿足結構的減重要求。本文根據齒輪箱承載方式及相關接口呎吋，利用三維設計軟件及有限元分析軟件，對懸掛結構進行多次優化與彊度計算。結果錶明，最終設計結構較初始設計結構彊度提高瞭23%，質量減小瞭12%。對實際結構進行瞭應力測試，計算結果與測試結果吻閤較好。

The suspended device of high-speed EMU gearbox is the important load-bearing components of driving de-vice,which can not only withstand the reaction of gearbox when the gear transmitting torque,but also can withstand the vi-bration and shock for each direction of the CRH train running at a high speed.So it should guarantee structure with enough strength and satisfy the requirement of the structure weight reduction when designing.According to the load mode of gear-box and the related interfaces size,optimized the suspended structure and calculated the strength many times with the 3D de-sign software and the finite element analysis software,the results showed that comparing with the initial designed structure, the strength of final designed structure increased 23%,the weight decreased 12%.Meanwhile,did the stress tests for the actual structure,the calculation results were close to the test results.
