Abstract

In order to evaluate the performance status of the speed sensor for the key components of EMU (Electric Multiple Units), according to the main environmental factors experienced by the service life-time, the type test scheme and corresponding detection requirements of the speed sensor are formulated. Combined with the test results after each type test, the performance status of the speed sensor is checked, the main faults occurring are summarized, and the failure analysis is carried out. The speed sensor is not a full-life product (less than 30 years), so it is recommended to repair it in fifth class, and the main failure location and failure stress of the product are found out, which provides important basis for the maintenance of the repair cycle and repair system.
