    Abstract
  • Through analyzing the stress and stiffness series parallel relations of correlative structures, the geometry and stiffness parameters determining the shear stiffness of wheelsets radial device for K7 sub-frame self-steering radial bogie were defined, and the mathematic calculating formula for the shear stiffness of wheelsets radial device was established. Based on vehicle system dynamics analysis technology, the required shear stiffness of wheelsets radial device was determined as 11 MN·m-1. Considering the practical constrained conditions of bogie structures, the matching design of geometry and stiffness parameters for the components of wheelsets radial device was carried out. First of all, the diagonal brace angle and axial tension-compression stiffness of link bar were respectively determined as 42° and 150 MN·m-1. Further, the required structural transverse stiffness of sub-frame, deduced by the mathematic calculating formula of shear stiffness, should not be below 23.6 MN·m-1. Then, aiming at the requirement of the parameters, the corresponding structural design of sub-frame was carried out. Considering the contact fitting relations among different components, the high-precise nonlinear FE assembly analysis model of wheelsets radial device was established. Calculation result shows that the final structural transverse stiffness is 24 MN·m-1, so the design requirement for the shear stiffness of wheelsets radial device is achieved. The calculated shear stiffness is 11 MN·m-1 and equals to the required design value, so the reliability of mathematic calculating formula and design method for the shear stiffness is verified.
