Accelerated degradation testing (ADT) is commonly used to obtain degradation data of products by exerting loads over usage conditions. Such data can be used for estimating component lifetime and reliability under usage conditions. The design of ADT entails to establish a model of the degradation process and define the test plan to satisfy given criteria under the constraint of limited test resources...
Reliability study of electronic system with the physics-of-failure method has been promoted due to the increase knowledge of electronic failure mechanisms. System failure initiates from independent failure mechanisms, have effect on or affect by other failure mechanisms and finally result in system failure. Failure mechanisms in a non-repairable system have many kinds of correlation. One failure mechanism...
This paper applies the constant vibration stress accelerated degradation tests to study the effects of random vibration on the parameters stability of quartz flexible accelerometer. Two stress levels of the accelerated degradation test (ADT) are conducted where random vibration spectrum is experienced by accelerometers in the transportation. Then two-step analysis method based on the pseudo life is...
The theory and characteristics of the accelerated life test (ALT) and the accelerated degradation test (ADT) is introduced. Based on the discussion about the classification and characteristics of gyroscopes, the accelerated test technology of mechanical gyroscopes and optic gyroscopes is summarized, including test types, stress, accelerated models, failure criterion and some other fundamental test...
Accelerometer is a sensor which converts acceleration that acts on the transport input shaft to an electrical signal by a variety of means of measurements. Acceleration will change into velocity by integration, while acquire the position information by the second integration. Through measuring linear acceleration of vehicle along the certain direction by accelerometer, inertial navigation system can...
