Simulation Analysis of Track Wear in Curve Sections of Mountainous Passenger Rail Line
摘要
Abstract
This paper mainly studies the amount of wear and operational safety of the mountainous passenger trans-port line with numerical simulation as the means. Based on Kalker linear creepage theory, using Elkins wear index model for reference, applying SIMPACK software to establish the CRH2 EMU, and taking the effects of track and tread irregularity and the elastic foundation effect, the paper calculates the creepage rate and force, and analyzes the effect of curve radius on the creepage rate, wear of rail, load reduction rate and derailment coefficient. Mean-while, the dynamic performance of both treads is compared under the conditions of six different curves. The results show that with half of the circular curve radius, the wear amount of left track increases about 6 times. Finally, the paper proposes some relevant advice to the design theory on mountainous railway line for passenger traffic from the perspective of the amount of wear and operational safety.关键词
