基于灰色理论的天津大气环境中SHPC钢初期腐蚀预测研究

Research on initial corrosion prediction of SHPC steel in Tianjin atmospheric environment based on grey theory

应用灰色理论GM (1, 1)模型对车辆常用金属钢SHPC在天津大气环境中的初期腐蚀失重量建立了预测模型,模型经检验显示出良好的精度和合理性,预测值与实际测定值非常接近,说明该方法可真实的反应腐蚀失重的实际情况,预测可靠性较高。

The grey theory GM(1,1)model was used to establish a prediction model for the initial corrosion loss of the vehicle’s common steel SHPC in Tianjin atmospheric environment.The model has been tested to show good accuracy and rationality.The predicted value is very close to the actual measured value,indicating that the method can truly reflect the actual situation of corrosion weight loss and the prediction reliability is high.
