RELIABILITY ANALYSIS OF DISTRIBUTOR VALVE OF AIR BRAKE SYSTEM FOR FREIGHT WAGON

Abstract

The results of distributor valve fault tree analysis are presented in this paper. A brief description and procedure of fault tree analysis are given in the first two parts. The reliability of the distributor valve is extremely important for the functioning of the air brake system. For this reason, reliability analysis of distributor valve based on the time to failure is shown in this paper. The distributor valve should react to changes in brake pipe pressure and provide the corresponding pressure in the brake cylinder.
