中文摘要:
      目的 研究模拟惯性器件贮存环境温度变化的加速环境谱与加速试验方法。方法 监测样品贮存环境温度应力变化的同时, 检测样品性能的变化, 通过雨流计数法将温度变化曲线转化为温度环境谱后再转换为加速环境谱, 依照加速环境谱开展试验, 通过试验结果与自然贮存样品性能比对, 开展试验样品性能评价。结果 以2012年某试验库房的温度数据为例, 通过转换得到了模拟惯性器件贮存环境的环境谱和加速环境谱, 并得到了用于指导惯性器件加速试验的方法。结论 将雨流计数法用于处理惯性器件经历的温度曲线, 转化得到的加速试验方法, 可以较好地模拟惯性器件贮存实际经历的温度变化过程, 指导对惯性器件的性能变化趋势进行预测和评价。
英文摘要:
      Objective To study accelerated environment spectra and accelerated test method that could simulate temperature change in the storage environment of inertial navigation components. Methods The characteristic parameter change of products was simultaneously tested when monitoring the temperature stress change of the storage environment, and the temperature change curve was converted into temperature environment spectra and then accelerated environment spectra by rainflow cycle counting algorithm. Accelerated test was performed according to the accelerated environment spectra, and the performance assessment of the product was conducted by comparing the results of accelerated test and natural storage test. Results Using the temperature data monitored in a test storage room in 2012 as an example, the environment spectra and accelerated environment spectra of the simulated storage environment of inertial components were obtained by conversion, and the method to guide accelerated test of inertial components was also obtained. Conclusion The accelerated test method obtained by conversion using rainflow cycle counting algorithm to deal with temperature stress of inertial components could well simulate the actual temperature change during the storage of inertial navigation components, and would be able to evaluate the life and capability change of inertial navigation components.
