Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 262, 2014. doi:10.4203/ccp.104.262

Keywords: torsional rigidity, dynamics performance, fatigue strength, frame.

Summary

In this paper an improved torsional rigidity test method is proposed by referring to the definition of bogie torsional stiffness in the standard JIS E4207-2004. The improved test method is simple and practical, and the errors can be effectively controlled within 7%. According to the structural type design, the frame may be classified as a box beam type frame or a pipe beam type frame. The study showed that the torsional rigidity of the pipe girder structure frame is smaller than the box girder structure frame. The SIMPACK and ANSYS software was used for simulation analysis on the two types of bogie. The results show that: curve negotiation performance of the pipe girder bogie is better, the derailment resistance is stronger and the safety factor is higher, than the box beam bogie. The area of architecture, such as beam and side beam connection position, greatly influenced the distortion deformation. The box girder type frame distortion mode frequency is higher; and its dynamic stress amplitude is lower than the pipe girder type of frame.
