摘要:

通过密封式电磁继电器的退化参数进行产品贮存寿命预测,来提高产品各阶段的可靠性。以灰色GM(1,1)模型和BP神经网络模型为基础,通过加权组合单一预测方法构建组合预测模型,利用误差最优最小二乘法、均方误差倒数法、等权分配法优化了组合权重值。通过精度最优的组合预测模型预测密封式电磁继电器的贮存寿命为13.17 a。结果表明,优化权重值的组合预测模型能够有效提高预测精度,为预估和提高该类产品在重要领域的工作可靠性提供了新思路。

Abstract:

Through the degradation parameters of the sealed electromagnetic relay,the prediction of the product storage life is used to improve the reliability of each stageof the product.Based on the grey model and the BP neural network model,the combined prediction model is constructed by the weighted combined single prediction method,and the combined weight value is optimized by using the error optimal least square method,the reciprocal of mean square error method and the equal weight distribution method.The storage life of the sealed electromagnetic relay is predicted to be 13.17 years by the combined prediction model with the best accuracy.The results show that the combined prediction model with the optimized weight value can effectively improve the prediction accuracy,which provides a new idea for predicting and improving the reliability of such products in important fields.

Key words: storage life, combined forecasting model, weighted optimization, electromagnetic relay
