Abstract:
The geometric sizes of bogie frame for motive power units were carried on by using the parametric design based on the mechanical method of structural mechanicst. The procedure was completed by Microsoft Visual C++6.0. According to the primitive parameters of the frame, the specified load and the load cases of the standard UIC 615-4—2003, the allowable stress of material, the overall sizes of the frame and the geometric sizes of different sections were educed, and the biggest nominal stresses of the frame under the load cases were analyzed. Through the comparison of calculational stresses and allowable stresses, the rationality of the frame's structural sizes was inspected. Calculation result indicates that in the design process of the frame, according to the standards UIC 615-4—2003 and EN 13749—2005, under load cases 1～13, the von_Mises stresses are less than 230 MPa, which is the allowable stress of 16Mn material. Under load case 14, the von_Mises stress is less than 345 MPa, which is the yield limit of 16Mn material. The static strength of the frame meets the design requirements. Obviously, the design effectively defines the frame's geometric sizes, and improves the frame's design efficiency. 2 tabs, 7 figs, 10 refs.
