浅议振动类课程教学中的动力减振器

A BRIEF DISCUSSION ON DYNAMIC VIBRATION ABSORBERS IN THE TEACHING OF VIBRATION COURSES

  • 摘要: 动力减振器是振动类课程中重要的内容,理论严谨,工程应用广泛,但该部分内容在教与学两方面都相对比较困难的。作者回顾并总结了邓哈托、铁摩辛柯直到最近的振动类经典教材关于动力减振器的描述。依据附加系统阻尼比的本身的定义,使用变量代换,简化并给出了最佳阻尼比参数的获取过程,同时对减振器理论分析的全过程给出了教学上的几点建议,期望能促进动力减振器内容的教与学。

     

    Abstract: Dynamic vibration absorbers (DVA) are an important part of vibration courses, with rigorous theory and wide engineering applications. However, this aspect poses challenges in both teaching and learning. The author reviews and summarizes descriptions of dynamic vibration absorbers in classic vibration textbooks by Den Hartog, S.Timoshenko, and others until recently. Based on the definition of the additional system damping ratio, the author uses variable substitution to simplify the process and provides a method for obtaining optimal damping ratio parameters. Additionally, several teaching suggestions are provided for the entire process of dynamic vibration absorber theoretical analysis, with the hope of enhancing the teaching and learning of dynamic vibration absorber content.
