摘要/Abstract

摘要： 制造业是我国碳排放的主要源头，高能效绿色机床装备是制造业实现“碳达峰、碳中和”目标的关键，机床的动态特性分析与能耗建模是机床绿色设计的重要环节。以五轴联动数控机床的各子轴系统为研究对象，针对其能量交互不明晰、自由度高、结构复杂的特点，基于键合图理论建立动力学特性数学模型和能耗模型。该模型综合考虑了机床各子轴系统动态特性和对能源消耗具有强关联性的关键变量，并利用Matlab-Simulink仿真工具建立了动态仿真模型。仿真分析和实验验证结果表明，所提出的基于键合图理论的动力学特性数学模型和能耗模型是合理且有效的。该模型对于深入分析各子轴系统的动态特性，了解其能量传递过程，指导其高能效优化设计，具有现实的指导意义。

Abstract: The manufacturing industry is the main source of carbon emissions in our country. High-efficiency and energy-saving machine tools are the key to the manufacturing industry to achieve the goal of "emission peak" and "carbon neutrality". The dynamic characteristic analysis and energy consumption modeling of machine tools are important parts for their design with energy-saving. This paper takes the sub-axis systems of the five-axis CNC machine tool as the research object. In view of its characteristics of unclear energy interaction, high degree of freedom and complex structure, a mathematical model of dynamic characteristic and energy consumption model are established based on bond graph theory. The dynamic characteristics of the sub-axis systems of the machine tool and the key variables which are strongly related to the energy consumption model are comprehensively considered. Then, a dynamic simulation model is established by using the Matlab-Simulink. Simulation analysis and experimental verification results show that the proposed mathematical model of the dynamic characteristic and energy consumption model based on bond graph theory is reasonable and effective. The model has practical guiding significance for in-depth analysis of the dynamic characteristics of the sub-axis systems of the machine tool, understanding of its energy transfer characteristics, and guiding its high-efficiency optimization design.

Key words: energy consumption modeling, dynamic characteristic analysis, five-axis linkage, bond graph
