Abstract:
      In order to explore the test method of military equipment limit boundary conditions. The HALT test technique is introduced in this paper. Based on the statistics of all kinds of fault case in the early equipment test, the relay which is widely used in the equipment and has frequent faults is selected as the research object. It explores the application of conventional environmental test equipment, designs halts test, and studies the technology and method of reliability assessment of relay under limit boundary conditions. When the low temperature –30 ℃ and high temperature 70 ℃ step stress are carried out, as well as the temperature range from –70 ℃ to +120 ℃, the detection data of electromagnetic relay are normal; In the vibration step test, sine constant frequency test is used. The initial acceleration value is 5g, and the step value is 5g. When acceleration is 30g, the solid state relay fails. The conventional test equipment can carry out halt test. Through the halt test results of the relay, the low temperature operation limit of the two types of relays is –70 ℃, the high temperature operation limit is 120 ℃, the vibration working limit is 50 Hz, 30g. The failure analysis and temperature/vibration comprehensive test will be continued in the follow-up, and the test design method and test method will be explored and improved.
