Abstract
Through establishing the trailer/semi-trailer integral axle mechanical model, analyzing the force conditions under the vertical load (impact dynamic load) and the tangential load (braking torque) of the axle from theoretic. Aid the ADAMS conduct the force simulation analysis for the 11 tons trailer/semi-trailer's integral axle. Furthermore, analyze the fracture mechanism of XCQ16 seamless sample through the tensile and impact fracture specimens by SEM scanning.
