摘要 对一种新型的减振降噪阻尼锯片进行了介绍,提出结合面的"球-平板"接触模型。基于该接触模型和赫兹理论,弄清了该类阻尼接头锯片减振降噪的机理,推导出了球-平板法向接触能耗的计算公式,并通过有限元仿真研究得到了在法向载荷作用下阻尼接头应力分布云图,揭示了最大应力与接触半径之间的关系以及弹性势能的变化量,为后续阻尼接头锯片的优化提供了理论参考。 A new type of vibration-damping and noise-reducing damping saw blade is introduced and the'ball-plate'contact model of the joint surface is proposed in this paper.Based on the contact model and Hertz theory,the mechanism of the vibration and noise reduction of the damping joint saw blade is clarified,and the calculation formula of the ball-plate normal contact energy consumption is derived.The damping joint stress distribution cloud diagram under normal load is obtained by finite element simulation and reveals the relationship between the maximum stress and the contact radius and the variation of the elastic potential energy,which provides a theoretical reference for the optimization of the subsequent damping joint saw blade.
