Typical Failure Forms and Cause Analysis of High Speed Railway Wheels

Abstract

In recent years, high speed railway technology has developed rapidly in China. Long routing of high-speed trains, low temperatures, corrosive environments and sand damage are unique to China’s operating environment. As an important safety component of rolling stock, the safety and reliability of the wheels is of deep concern and high value. It is significant to carefully study and systematically summarize the damage from different failure types in high-speed railway wheels under current conditions, and determine the influencing factors and mechanisms of wheel failures in order to improve railway operation safety. In this paper, the damage forms of high-speed railway wheels in China are introduced, and the main influencing factors of wheel failure are discussed in combination with wheel damage characteristics. What’s more, damage mechanism is analyzed aiming at providing theoretical references for reducing failure rate and improving train operation quality.
