Abstract

Abstract: The application and working principles of permanent magnetic track brake（PMB）of rail vehicle were briefly introduced. The characteristics of current PMB were analyzed and a double permanent magnet systems track brake（D-PMB）was proposed. According to the structure of the proposed D-PMB, the design method of main structure parameters was elaborated and the structure parameters were designed. The attraction characteristics of the designed D-PMB were tested by software simulation. The results show that the designed D-PMB makes up for the defect of PMB and the parameter design based on magnetic circuit theory satisfies the performance requirements of PMD.
