Emulation and Prediction of the Cold Roll Forming Force

In order to optimize the craft parameter of cold roll forming, this paper puts forward a new method reflect the law between cold roll forming force and craft parameter. The method combines artificial neural network and finite element emulation for cold roll forming, and begins with analyzing the cold roll forming to decide the main factors that have an impact on roll forming force. According to the single factor experiment method, the paper establishes the roll forming emulation model to simulate, and a BP neural network is constructed with the sample data from the simulation.
