摘要

我们在开发单自由度再生车削颤振动态模型时考虑了工件的小质量偏心。本研究对再生车削颤振进行了数值和分析，重点关注工件的小质量偏心。通过使用数值方法，研究了小质量偏心如何影响各种初始状态下的车削颤振分岔特征。主要集中在应用多重尺度法分析小质量偏心和工件角速度对车削颤振主共振的影响。根据本文的研究，在整个车削过程中不能忽视质量偏心。

Dynamics of the regenerative turning chatter with little mass eccentricity

The little mass eccentricity of the workpiece is taken into account when we develop a single-degree-of-freedom regenerative turning chatter dynamic model. This study provides a numerical and analytical analysis of regenerative turning chatter, with a focus on the little mass eccentricity of the workpiece. By using a numerical approach, it is examined how a little mass eccentricity affects the turning chatter bifurcation features in various initial states. It primarily concentrates on applying the multiple scale method to analyze the impact of little mass eccentricity and workpiece angular velocity on the primary resonance of turning chatter. According to the research presented in this paper, mass eccentricity cannot be disregarded throughout the turning process.

期刊介绍： The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear. The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas. Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
