| 目的 明确某机械陀螺在贮存环境下的环境敏感参数。方法 以机械陀螺在热加速老化试验中的各项性能参数检测结果为基础，依次对各参数检测数据进行能表征参数退化程度的无量纲转化，分析参数相对于原始值的偏离程度以及环境敏感程度，偏离度最大的参数即为陀螺的主要环境敏感参数。结果 解锁误差、接触起始角、垂直漂移、水平漂移参数的偏离程度分别为1041.7、1248.3、1472.7、417.7。垂直漂移参数是该机械陀螺在贮存环境下的主要环境敏感参数。结论 提出的分析方法可有效用于多参数产品的环境敏感参数分析。 |

| The paper aims to determine the environment-sensitive parameters of mechanical gyroscope in storage environment. Based on the test results of mechanical gyroscope in thermal accelerated aging test, each parameter was converted to a dimensionless parameter that can characterize its degree of degeneration, then the deviation degree of each parameter relative to the original value and the sensitivity of each parameter to the environment were analyzed. The parameter with the largest deviation was considered as the main environment-sensitive parameter of mechanical gyroscope. The deviation degrees of unlocking error, contact start angle, vertical drift and horizontal drift parameters were 1041.7, 1248.3, 1472.7 and 417.7 respectively. The vertical drift parameter was the main environment-sensitive parameter of mechanical gyroscope in storage environment. The method presented in this paper can be effectively used for environment-sensitive parameter analysis of multi-parameter products. |
