摘要

汽车覆盖件模具多采用镶块式模件拼接后整体加工，拼接区加工时易引发载荷突变产生冲击振动，影响拼接区的整体加工质量，为了提高拼接区的加工精度，对铣削过程的时域振动信号进行前瞻预测。首先基于互补式集合经验模态分解方法将铣削振动信号进行6层模态分解，得到各层本征模态函数及趋势序列；然后分别构建不同工况下的支持向量回归预测模型，采用灰狼优化算法对支持向量回归中的参数进行寻优分析；最后对时域振动信号进行重构和前瞻预测。试验结果表明，在淬硬钢拼接区铣削过程中，结合CEEMD和GWO-SVR的铣削振动信号前瞻预测方法相较于其它传统方法具有更良好的预测效果，在预测时间为0.12秒时总体预测准确率达94%以上。

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%.
