摘要

为评估DTECS-2 在实际使用振动环境下的可靠度，通过应力- 强度模型推导出使用可靠度计算公式，并基于振动步进应力试验数据和DTECS-2 实测运行振动环境数据，计算得出DTECS-2 在实际使用振动环境下的可靠度为0.997 3。

Abstract

To assess the reliability of the DTECS-2 in working condition, stress-intensity models were used to deduce a formula for calculating using reliability. Based on vibration stepping test data and DTECS-2 actual vibration environment data, reliability degree of DTECS-2 in actual vibration environment was obtained, which was 0.997 3.
