A design of bearing life prediction program based on BP neural network

Based on BP neural network theory,this paper establishes a bearing residual life prediction model by using parameters of bearing under unload and load operation.Bearing data samples are learned and trained in MATLAB to obtain more accurate weights and threshold of BP neural network and to obtain m function file through BP neural network algorithm.A COM component is generated in MATLAB.DLL files in the COM component are called in the software interface made by Visual Basic 6.0.Solving the problem of algorithm optimization and module calls,this paper successfully develops a bearing life prediction software for the management of quality control of mechanical and electrical products.
