摘要
悬臂梁作为木材加工的重要部件,其振动情况直接影响加工中心的加工精度和使用寿命。针对加工中心悬臂梁的振动问题,通过理论分析建立悬臂梁模态分析的数学模型,对悬臂梁的振动原理进行阐述;通过数值计算,对悬臂梁处于自由模态和约束模态的振型和频率进行求解。结合悬臂梁外部激励情况,对其振动情况进行分析,基于此为悬臂梁的设计优化提供依据,所得研究成果具有一定的理论和应用价值。
As an important part of wood machining center, the vibration of cantilever beam directly affects the machining accuracy and service life of the wood machining center. Aiming at the vibration problem of cantilever beam of wood machining center, the mathematical model of the modal analysis of the cantilever beam is established by theoretical analysis, and the vibration principle of the cantilever beam is expounded. The shape and frequency of the cantilever beam in free mode and constrained mode are solved by numerical calculation. Combined with the external excitation of the cantilever beam, the vibration of the cantilever beam is analyzed. Based on this, it provides a basis for the design optimization of the cantilever beam, and the obtained research results have certain theoretical and practical value.
