基于灰色关联理论分析水面舰船环境对数字多用表贮存性能的影响

目的评价水面舰船环境中温度、湿度和盐雾环境因素对数字多用表贮存性能影响的敏感性。方法模拟水面舰船舱室环境,开展贮存环境试验,测量数字多用表的性能数据和贮存环境数据。通过灰色关联分析,评估不同环境因素对数字多用表贮存性能影响的敏感性。结果分析了四种模拟舱室环境、两种型号数字多用表的贮存性能受温度、湿度和盐雾环境影响的关联度。结论采用灰色关联理论研究环境因素对数字多用表贮存性能的影响,并对比关联度计算结果发现:温度影响最大,湿度其次,盐雾影响最小。

Influences of Surface Ship Environment on Storage Performance of Digital Multimeter Analyzed Based on Grey Relation Theory

Objective To evaluate the sensitivity of temperature, humidity and salt mist environment to the storage performance of digital multimeter in ship environment. Methods Surface vessel cabin environment was simulated to carry out storage environment test and measure performance data and storage environment data of the digital multimeter. Through grey relation analysis, the sensitivity of different environmental factors to the storage performance of digital multimeter was assessed. Results The storage performance of four simulated cabin environments and two types of digital multimeter were obtained by the correlation degree of temperature, humidity and salt mist. Conclusion Influences of the grey relational theory research environment on the storage performance of digital multimeter is researched. After comparing with the calculation on degree of association, the results show that the temperature has the greatest influence, the humidity is the second, and the salt mist was the smallest.
