Reliability of Relay Valve of Brake System for Rail Vehicles

  • Received Date: 10 Apr 2009
  • Publish Date: 20 Jun 2009
  • The reliability of relay valves of brake system for rail vehicles was investigated by endurance test. The results show that the failures of the relay valve can be described as a Weibull distribution with a shape parameter of 3.43,and the failure rate increases with an increase in test cycles,and fatigue failure of the V-ring and returning spring is the major failure for the relay valve.
