The invention relates to the technical field of tunnel excavators, in particular to a TBM
cutting tool life prediction method based on a
data driven support vector regression machine. The method comprises the following steps that 1, data of the TBM
cutting tool excavation site is collected; 2, driving factors that affect the TBM
cutting tool life is determined, and a sample
data set of the driving factors is established as a
training set; 3,a prediction model of a multi-kernel
support vector regression machine is constructed, the
training set is input, training is conducted on the prediction model to determine corresponding optimal parameters and penalty function C and insensitive
loss function parameter epsilon; 4, an optimal kernel function of the prediction model is determined; 5, the sample
data set of the driving factors of the cutting tools to be predicted serves as a prediction sample set, the prediction model is input, and a prediction result is obtained. According to the TBM
cutting tool life prediction method based on the
data driven support vector regression machine, a large amount of data of the excavation site is selected as parameters, and on the basis of a model based on support vectors regression
machine is constructed, and the accuracy of a prediction tool is improved.
