【Abstract】 Based on nonlinear FE software MARC, numerical simulation of BOM fastener mechanics in heavy load wagon is studied. The key technology in constructing the finite element model is discussed. The elastoplastic model is established based on contact process. The result of the numerical simulation reveals the law of BOM fastener plastic forming, which provides numerical evidence for ascertaining the pressure influence range of BOM fastener, and an important reference for the application of BOM fastener in heavy load wagon.更多还原
