Strength Calculation And Evaluation Of Wheelsets Using FEM
Abstract：With increasing speed, service environment increases the load bearing member diesel worse. As one of the main wheel bearing parts, the full weight of the vehicle by wheel exerted on the rail, the reliability of the structure is directly related to the comprehensive technical performance and driving safety of heavy-duty trucks. In the development of diesel, it should be the rational design of its structure. Therefore, it should be perfect for the strength analysis of the wheel at the design stage. This paper studies the internal combustion engine to the wheels of the analysis are discussed first at home and abroad, introduces the research on the current status of the internal combustion engine wheels. By using PTC's CreO2.0 software to create three-dimensional structural model of the existing Dong Feng 4B diesel locomotive bogie wheel, and using ANSYS software, according to the International Union of Railways UIC 510-5 organizations specified in the calculation of loads and calculation condition wheel strength finite element strength analysis.
Key Words：Wheel sets ；structural strength；static strength；finite element analysis
