Study On The Structure Of Equipment Cabins For EMU

To ensure the vehicle safety and high-speed running，The necessary equipment must behanging in the vehicle, which puts forward higher requests to the vehicle dynamiccharacteristics and t equipments must be reasonable.High-speed railway has put forwardhigher requirements for lighting car body, lightweight is bound to affect the stiffness of thebody. The previous vehicle structural design, analog design and experience design, Howevernew structure of a vehicle to meet new performance requirements.After reading a lot of relevant literature, on the basis of summing up the latest researchresults in domestic and foreign, With the FC05carbody of CRH3EMU as a carrier. Thearticle utilized finite element analysis sofeware HyperMesh, Ansys, etc, And considering thecarbody and equipment cabins as elastic body. Calculation the modal and static strength of theanalysis of body structure and equipment cabin.Then, study the vibration law of carbody thathanging equipments.assess the most adverse conditions. Provide a theoretical basis for acertain theoretical basis for the rational optimization of equipment hanging structure andimprove the safety of train operation equipment hanging and stability. Topology optimizationof the reservoir hanger strip structure with SIMP method. Put the basic theory of topologyoptimization and method into the vehicle structure design.With mode as a research to discuss the impact of different arrangement. With staticstrength analysis and optimized design as a method to optimize the structure. This articleincludes five parts: The first part is the first two chapters taht is the basics of preparation. Thesecond part,detailed introduction the structure of FC05carbody and equipment cabin,thenbuild finite element model. The third part,analysis of the body modes and explore a morereasonable arrangement of the Equipment under the vehicle. Part IV,computational analysis ofthe strength of the end of the cabin,identify the most unfavorable conditions. Part V,optimizethe design of reservoir hanger strip structure,and comparative analysis of the structure beforeoptimization and after optimization.
