| Abstract: | The paper compares the different points of two typical sub-frame radial bogies' radial organization.By analyzing horizontal force condition of the cross-bar sub-frame radial bogie,establishing equivalent model of bogie,and solving equations,the function expression of equivalent shear stiffness refer to the lateral installation span of the cross-bar can be concluded,which is used to analyze the influence of the geometry parameters to the dynamics performance,and simulation model on the SIMPACK is built to va... |
