| Abstract: | The service reliability and failure model of motor dump trucks are investigated in detail by using FMEA method and statistical data taken from extensive operation of heaven duty truck which has tonnage of 108. Key system as well as crux failure model to all of the trucks are detected, and a series of measures are proposed and testified to improve quality and clear fault. The result is showed that: the operational availability of dump truck used now is estimated at 55.2%,tow system and brake system are key system. Ring fire of motor by short circuit, no brake and no tow are crux failure model. |
