回归分析法在电磁继电器释放电压值预测中的应用

首先阐述了一元线性回归、指数回归、加权指数回归等3种回归分析方法的原理及各模型参数的确定方法.在此基础上,针对电磁继电器贮存加速寿命试验所得到的释放电压数据分析进行拟合与预测,并对各种回归分析方法的拟合与预测结果进行了精度分析.最后,对3种方法的预测效果进行了比较.

Application of Regression Analysis in the Release Voltage Forecasting of Electromagnetic Relay

The theories of three regression analysis methods were illustrated, which are simple linear regression, exponential regression and weighted exponential regression. Then, the model parameters were determined. On the basis of the theories, the release voltage value of electromagnetic relay in the accelerated storage life testing were fitted and forecased respectively. At the same time, the accuracy analysis for the results of fitting and forecast was made. Finally, the forecasting effectiveness of the three methods was compared.
