| 摘 要： | 在机床的高速加工过程中，因数控转台各种热源发热与变载荷的共同作用而产生热-力耦合效应，但当前的数控转台优化设计方法往往忽略了热-力耦合效应对转台动态特性的影响。在深入剖析国内外数控转台研究成果的基础上，提出探索热-力耦合效应及其产生的机理，建立转台的热-力耦合模型，得到高速数控转台热-力耦合动态特性。鉴于蜂窝结构具有良好的散热性及力学性能，提出研究基于蜂窝的转台仿生原理，获取高速数控转台热-力耦合仿生设计准则。以提高转台热-力耦合动态特性为目的，提出运用仿生设计准则对结构进行多目标优化，进而形成一套新颖的高速数控转台热-力耦合仿生优化设计方法。

| Abstract: | During the high-speed precision machining of the machine tools, the CNC turntable was subjected to variable loads and a variety of heat sources to produce a thermal-mechanical coupling effect. The current CNC turntable optimization design method often ignored the influences of the thermal-mechanical coupling effect on the dynamic characteristics of the turntables. The paper proposed to explore the thermal-mechanical coupling effect and the mechanism based on an in-depth analysis of the research results of CNC turntables, and then the thermal-mechanical coupling model of the CNC turntables was established to obtain the thermal-mechanical coupling dynamic characteristics of high-speed CNC turntables. In view of the good heat dissipation and mechanics properties of the honeycomb structure, the thermal-mechanical coupling bionic design criteria of high-speed CNC turntables was proposed based on the bionic principle. In order to improve the thermal-mechanical coupling dynamic characteristics of high-speed CNC turntables, the structural multi-objective optimization was carried out through bionic design criteria, and then a novel thermal-mechanical coupling bionic optimization design method of high-speed CNC turntables was established. |
