A Remaining Life Prediction Mechanism of Equipment Based on Group Method of Data Handling

This paper focuses on the issue of forecasting remaining life of the mechanical equipments for improving the ability of equipment troubleshooting. We propose a new method to perform the forecasting issues, which is different from traditional methods, applied to nonlinear complex systems and based on the Group Method of Data Handling (GMDH) theory. This method achieves the automated model creating and validating processes, and based on the phase space reconstruction theory, we reconstruct the prime driving power system, which effectively resolve the problem that can´t construct the system model caused by not enough state parameters of the GMDH methods.
