摘　　要： 随着切削速度的不断提高,对主轴/刀具联结的静、动态特性要求越来越高。传统的设计法不仅设计周期长,而且设计质量难以保证,已不适应新产品的研制开发需要。利用参数化有限元法完成高速旋转下的主轴/刀具联结的力学模型的建立和分析,并通过非线性二次规划法对其进行优化,不仅可以提高设计质量,而且可以大大缩短设计周期。研究结果表明,对于多约束优化问题,利用该算法可以较好地获得全局最优解,结构参数优化合理,能够满足工程实际应用的需要。 With the increase of the cutting speed, the static and dynamic performance of the spindle/toolholder interface is required higher and higher. The traditional method, which not only has longer design cycles, but also doesn't gain the optimum results usually, can't meet the requirement of researching and developing products. The parametric finite element method (FEM) was used to establish and analyze the mechanical model of the spindle/toolholder interfaces, and the nonlinear quadratic programming method applied for the optimum design of the structures. It can not only improve design quality, but also shorten design cycles. The result of this study shows that a global optimum solution can be guaranteed with multiple restrains, optimal structural parameters are reasonable, and can meet the needs of the engineering application.
