| Abstract: | Aiming at the storage-life of MEMS Inertial Navigation System, the experiment on accelerated life is studied. The performances and primary indices of MEMS INS are introduced. Based on the principle of accelerated life testing and characteristics of the key components in MEMS INS,. the acceleration stress, the stress level and the acceleration model are designed, and then the test project is established. The theoretical analysis on the data in weibull distribution is also put forward, thus the life of productors can be estimated. |
| Keywords: | MEMS INS accelerated life stress acceleration with constant temperature acceleration model |
