摘要
基于多因素敏感性分析方法,对影响塌角大小的各参数进行了敏感性分析。结果表明,毛坯内径和毛坯滚道倾角是影响塌角缺陷的敏感因素。通过敏感性分析找出了敏感性因素,这能为毛坯的优化设计提供重要的理论依据。
Based on the multi-factors sensitivity analyzing method, the sensitivity of the influential parameters of sunking defect was analyzed. The results show that blank inner diameter and blank raceway angle are the sensitivity parameters of affecting sunking deflect. Through the sensitivity analying, the sensitivity parameters were found out, which can provide an important theoretical basis for the blank optimization design.
