Reliability Of Automobile Relay Life Test Research Under The Conditions Of High And Low Temperature Alternating

Along with the development of modem life,the requirement of comfort for people is gettinghigher and higher,the reliability requirement of automotive is geeing higher and higher too Asone ofthe most widely used electronic components,automobile relay'S reliability is taking moreand more attentionAt present,there is a lot of study on automobile relay in domestic and international,but it isrelatively small on the temperature of the impact on automotive relays reliability．In this paper,w-e have a brief analysis on the factors that a~'ect the reliability of automotive relays。Developeda reliability of automotive relay life test program under high and low-temperature conditions,designed the circuit to test the program and compiled the control software Done the life testabout car relay reliability under the high and low-temperature akernating conditions Through thetest and the failure analysis of metallographic analysis about the sample contacts,researching theinfluence of automotive relay contacts Reliability under high and low-temperature...
