Abstract

The main purpose of this article is to investigate the bursting oscillations of the medical shaking tables resulted from friction in practical application. Using the theoretical method of linear loading, the analytic expression of friction acting on an eccentric turntable is derived in detail. Besides, through numerical simulation, the decisive role of friction in bursting oscillations is verified. On this basis, several practical operation plans are proposed to eliminate harmful vibrations. Last but not least, the effectiveness of theoretical methods is validated through example calculations in cases with special parameters.

受干摩擦影响的带有偏心转盘的台式医用振动器的爆破振动机制

本文的主要目的是研究医疗振动台在实际应用中因摩擦而产生的爆裂振荡。利用线性加载的理论方法，详细推导了偏心转盘上摩擦力的解析表达式。此外，通过数值模拟，验证了摩擦在爆裂振荡中的决定性作用。在此基础上，提出了几种消除有害振动的实用操作方案。最后但并非最不重要的一点是，通过对具有特殊参数的情况进行实例计算，验证了理论方法的有效性。
