摘要
为提高钻削工艺生产效率,同时得到与产品所需精度相匹配的参数,提出一种基于LSSVR的多响应模糊参数优化方法。首先,通过犹豫化处理,全面度量噪声干扰,增强参数设计的稳定性。其次,将灰色关联分析与LS-SVR相结合进行参数设计,获得最优模糊参数组合。最后,将所研究方法应用于AISI 304不锈钢钻削过程的实证研究中,得到3组优化参数组合,为生产决策者提供更多选择,有效解决了参数精度与生产条件不匹配的问题。
To improve the productivity of drilling process and obtain the parameters matching the required precision of the product,a fuzzy parameter optimization approach of multi-response based on LS-SVR was proposed.Firstly,the hesitant processing measured the noise comprehensively,which enhanced the stability of parameter design.Secondly,grey relational analysis was combined with LSSVR for parameter design to obtain the optimal fuzzy parameter combination.Finally,the studied method was applied to the empirical research on the drilling process of AISI 304 stainless steel.Three sets of optimized parameter combinations were obtained,which provided more choices for production decision-makers.The optimized parameter combinations effectively solved the problem that the parameters’accuracy did not match with its production conditions.
