Application of ANSYS Finite Element Analysis in the Study of Machine Tool Spindle Vibration Characteristics and Structural Optimization
摘要: 本研究旨在运用ANSYS有限元分析软件深入研究机床主轴系统的振动特性。作为机床关键组件之一，主轴在确保加工精度和质量方面具有重要作用。通过静态结构分析、模态分析、谐响应分析以及结构优化，全面计算并研究了机床主轴的前六阶模态参数。研究结果显示，主轴振动主要呈现为径向跳动。优化仿真进一步表明，优化后的主轴相较于未优化前在总变形和应力方面均有所降低，有效提高了机床的工作性能。本研究为深入了解机床主轴振动特性及其优化提供了重要见解，对于提高加工精度和机床整体性能具有积极意义。
Abstract: The present study aims to comprehensively investigate the vibration characteristics of machine tool spindles utilizing ANSYS finite element analysis software. As a crucial component of machine tools, the spindle plays a pivotal role in ensuring machining precision and quality. Through static structural analysis, modal analysis, harmonic response analysis, and structural optimization, the study extensively computed and explored the first six-order modal parameters of the machine tool spindle. The research findings reveal that the predominant vibration of the spindle manifests as radial runout. Subsequent optimization simulations indicate that the optimized spindle exhibits reduced total deformation and stress compared to its pre-optimized state, effectively enhancing the operational performance of the machine tool. This study provides significant insights into understanding the vibration characteristics of machine tool spindles and their optimization, holding paramount importance in advancing machining precision and overall machine tool performance.
