Structure Sensitivity of the CRH3 EMU Based on FEM
The bodywork structure sensitivities can provide modification direction information in structure design and optimization of railroad trains. This research focuses on the high speed CRH3 train set bodywork, in which the finite element model is established by implementation of Hypermesh software, meanwhile the models are performed by use of finite element method. The chassis, side wall, top plate, end wall and other part thicknesses are used as the design variables, and consequently the sensitivities of the CRH3 bodywork modal frequencies to the design variables are achieved by use of numerical differential method. Results show that the sensitivities of the modal frequencies to the chassis and the side wall are maximum and to the top plates are lesser. For the end wall and the chassis front end, the sensitivities are negative.
