| In this thesis, on the basis of extensive reading literature and research, the design and development of 100t large-scale electric flat car is introduced, and by using SolidWorks, the stress and deformation of the flat car body structure are analysed, and with the orthogonal experimental design and finite element analysis combined method, the flat car body structure is optimized.The main works in this thesis are as follows:1. According to Seri company's 460 projects's requirements, researched and developed a new type of 100t large-scale electric flat car. Introduces the performance parameters, working principle and main structure of the flat car, especially introduces the conductive devices, insulation systems of the large-scale electric flat car which has patented and introduces innovative design of the braking system.2. Use COSMOSXpress function of SolidWorks, do force analysis with the 100t large-scale electric flat car's body structure, acquire equal distribution of stress and displacement diagrams which provides the basis for design and optimize the large-scale electric flat car body structure.3. Conducted on the body structure of the orthogonal experimental design, by analyzing the test results, obtained excellent level, excellent mix of body structure design, and the extent of various factors affect the body structural design, provides theoretical basis to further optimize the body structure.This new 100t large-scale electric flat car actually used in the production, using for 3 years, performed well, there is no failure, showed that new 100t large-scale electric flat car's design is reasonable, especially the unique design of conductive devices and insulation systems work effectively and reliably. |
