Specifically reflected in the following aspects: 1. Optimizing anti-vibration design of equipment: The company can optimize the vibration-damping structure of control cabinets (e.g., adopting damping materials, improving fastener design), develop anti-vibration insulation components, and formulate product reliability standards applicable to high-vibration environments by analyzing the impact of vibration frequency on insulation resistance, thereby significantly improving the long-term operational stability of equipment under mechanical vibration operating conditions. 2. Promoting industrial technological progress: This dataset can provide experimental support for the R&D of electrical equipment in vibration-sensitive sectors such as rail transit and shipping, advancing research on anti-vibration insulation materials, the development of vibration fatigue life prediction technology, and the improvement and upgrading of vibration testing standards in relevant industries. 1. Data Collection: Real-time recording of insulation resistance test data for electrical control cabinets under varying vibration frequency conditions, including fields such as test sample ID, test timestamp, vibration frequency (unit: Hz), insulation resistance (unit: MΩ), etc. 2. Data Preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate all historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the insulation resistance field within dataset X. 3. Calculation of Linear Regression Slope a and Intercept b: (1) Based on dataset X, with vibration frequency as the independent variable and insulation resistance as the dependent variable, use the SLOPE function to determine slope a and the INTERCEPT function to determine intercept b, both based on the principle of least squares. (2) Slope a represents the degree of influence of a unit change in vibration frequency on insulation resistance, while intercept b represents the insulation resistance value of the electrical control cabinet under the reference vibration frequency. 4. Application of Results: (1) Calculate the proportional coefficient k: k = |a / average insulation resistance| × 100%. (2) Classify the impact level as "high impact" if k ≥ 15%, "medium impact" if 8% ≤ k < 15%, and "low impact" if k < 8%.
