摘要
目的分析敏感器的加速寿命试验方法,为下一步试验的实施奠定基础。方法采用步降应力加速寿命试验方法,利用逆矩估计法和最优线性无偏估计方法对数据进行分析。结果确定了加速试验所需的各项参数,为数据处理提供了理论依据。结论利用逆矩估计法和最优线性无偏估计方法对各参数进行估计是有效的,能够分析出样品的各可靠性指标。
Objective To analyze the accelerated life test (ALT) of sensors so as to lay foundation for further tests. Methods The ALT was conducted and the data was analyzed by methods of inverse moment and best linear unbiased estimation (BLUE). Results Each parameter for the test was determined, which provided evidence for data processing. Conclusion Using inverse moment and BLUE to estimate each parameter was effective, and could analyze each index of sample reliability.
