摘要
针对叶形板簧加工在流程工艺及噪声因素共同作用下出现的成型不确定及质量低劣的现状,提出采用稳健性参数设计的方法对叶形板簧的加工过程进行参数控制以达到质量控制的目的。以叶形板簧的自由高度作为优化目标,加热温度、加热时间、传送时间、成型时间为可控因子,淬火油温度为噪声因子,分别采用田口方法和双响应曲面法确定了叶形板簧加工工艺的稳健性参数;并在此基础上对这两种常用的稳健性设计方法从效率、理论依据以及优化结果三个方面进行对比,分析两种方法的有效性及其优缺点,以对产品过程质量控制的稳健设计提供借鉴。
Due to the interaction between process and noise factors,the confectioning process of leaf spring is prone to be uncertain and with poor quality.This paper proposes an approach of robust parameter design to control the confectioning process of leaf spring,and thus achieving quality control.We set leaf spring free height as the optimization target,heating temperature,heating time,transfer time and forming time as controllable factors,quenching oil temperature as noise factor.Then the robust parameters of the confectioning process of leaf spring are given separately by Taguchi method and dual response surface method.Based on this,some compared analysis on the validity,merits and drawbacks of these two methods are presented from efficiency,theoretical basis and optimal results,thus offering some references to robust design on quality control of product process.
