振动环境下MEMS加速度计的可靠性评估
Reliability Evaluation of MEMS Accelerometer in Vibration Environment
摘要
Abstract
Based on the accelerated life test and accelerated degradation test of MEMS accelerometer,the reliability technology of MEMS accelerometer in vibration environment is studied. The failure mode and failure mechanism of MEMS accelerometer in vibration environment are analyzed by theory,the accelerated life test and accelerated deg-radation test scheme are designed,and the reliability evaluation of the failure data of MEMS accelerometer under vi-bration environment is carried out. The results show that the evaluation results of the two evaluation methods are ba-sically consistent. The accelerated performance degradation assessment method is suitable for the reliability study of MEMS accelerometer in vibration environment,and the method is simple,accurate and feasible. It can provide important reference for MEMS accelerometer in practical application.关键词
