| Popis: | The high precision quartz flexible (HPQF) accelerometers are characterized by high reliability, long life, small sample size and complex failure mechanism. It is difficult to evaluate the acceleration factor by traditional statistical methods. Based on the concept of characteristic life, a new method to evaluate the acceleration factor of the components of an HPQF accelerometer was proposed by employing the reliability prediction method for HPQF accelerometers and the Arrhenius-based accelerated life test model. Then, a storage life estimation model for HPQF accelerometers was proposed. Taking a certain type of HPQF accelerometer as an example, evaluation of the specific accelerating factor, and design and analysis of the storage life accelerated test plan, were performed to verify the engineering applicability of this method. |
