Integrated SAE-SOM-based wax mold casting heat treatment equipment health state evaluation method

The invention belongs to the technical field of digital twinning technology and equipment fault prediction health management, and discloses a wax mould casting heat treatment equipment health assessment method based on integrated SAE-SOM. According to the method, adaptive extraction of performance degradation characteristics of wax mould casting heat treatment equipment is realized, space mapping is carried out on extracted integrated characteristics according to characteristic evaluation indexes, and optimal class characteristic extraction is carried out in a characteristic space by adopting a K-means algorithm; training the health characteristics of the wax mould casting heat treatment equipment by adopting a self-organizing mapping network unsupervised training mode, and evaluating the health state of the wax mould casting heat treatment equipment by taking the minimum quantization error as output; and finally, verifying by using the twin data set and the actually measured data set of the wax mold casting
