Abstract

Auto cover molds are mostly processed as a whole after the splicing of insert-type modules. When the splicing area is processed, it is easy to cause sudden load changes and shock vibration, which affects the overall processing quality of the splicing area. In order to improve the processing accuracy of the splicing area, the time domain of the milling process Prospective prediction of vibration signals. First, based on the complementary ensemble empirical mode decomposition method, the milling vibration signal is subjected to 6-layer modal decomposition to obtain the eigenmode function and trend sequence of each layer; then the support vector regression prediction models under different working conditions are constructed respectively, and the gray wolf is used The optimization algorithm analyzes the parameters in the support vector regression; finally, reconstructs and predicts the time-domain vibration signal. The test results show that the forward-looking prediction method of milling vibration signals combined with CEEMD and GWO-SVR has a better prediction effect than other traditional methods in the milling process of the hardened steel splicing zone. The overall prediction is accurate when the prediction time is 0.12 seconds. The rate is over 94%.
