摘要: 本文探讨了机械加工中产生负刚度的理论条件。得出了大小不等的双刚度轴的存在是产生负刚度的基本条件。并通过理论计算与实验,提出利用从负刚度到正刚度的变化区来提高机械加工精度的有效措施。

关键词: 负刚度, 减振, 镗杆

Abstract: A theoretic condition of producing negative rigidity in machining is discussed in this paper. It is obtained that double rigidity axes, which differ in size, are basic condition of producing negative rigidity. By theoretic calculation and test, it is advanced that machining precision is raised effectively with the changing area from negative rigidity to positive one.
