摘　　要：主要研究了各种阻尼减振形式对齿轮传动轮体振动的影响,通过有限元软件ANSYSY计算得到一对齿轮传动周期性变化啮合力,对齿轮进行简化,将计算得到的啮合力作用到齿轮轮体上,比较齿轮轮体在添加阻尼前后的振动情况。结果表明对于单腹板齿轮,约束阻尼层的减振方式优于非约束阻尼层的方式,可以有效地降低腹板振动,减小噪声。The effect of various forms of damping on the vibration of gear body is studied.Firstly,the periodic meshing force of gear drive is obtained by the FEA software ANSYS.Secondly,the gear model is simplified,the meshing force is added to the gear body and the vibration before and after damping are compared.The result shows that,the single-web gear with constrained damping layer is better than the one with non-constrained damping layer,for constrained damping layer can effectively decrease web vibration and reduce noise.
