刚强约束的主轴结构设计研究
Research on Spindle Structure Design with Stiffness-Strength Constraints
摘要
Abstract
Aiming at the problems that the spindle structure was mainly designed by people based on their experience,the design results had a great correlation with human experience and might not fully consider the thermal influences and other factors,so it was difficult to realize the intelligent de-sign.By defining the geometrical structure functions of the spindle structures,establishing the strength constraints and stiffness constraints of the spindle structures,realizing the stiffness-strength coupling analysis of the spindle structures,and ultimately the expandable mathematical model was es-tablished for the design of the spindle structures.According to the established mathematical model of spindle structures,the spindle profile shape curve that meet the rigid-strong coupling requirements was obtained through numerical solving,and then,combined with the assembly requirements,the curve was transformed into a straight line profile that was easy to be processed by using the method of segmented straight line fitting,so as to obtain the straight line profile of each segment for the spin-dle,and to complete the design of the spindle structures based on the rigid-strong coupling.Finally,the spindle structure design of a vertical machining center was taken as an example to verify the cor-rectness and feasibility of the proposed method,which provides an intelligent basis for spindle struc-ture design.关键词
