策动力频率与方位角变化对念力转机旋转影响的研究

The Analysison How Force-frequency and Azimuthal Angle Influenceon the Rotation of Gee-Haw Whammy Diddle

影响机械性木材念力转机旋转的主要参量包括策动力频率、策动力与木材方位角、木材结构特征等。文章以正交各向异性木材为研究对象,采用横波偏振理论及传播特性分析了策动力频率、方位角变化与念力转机旋转间的关系,得出了旋转过程中出现顺时针转动、逆时针转动、旋转方向突变三种现象与策动力频率、方位角范围之间的对应关系,为研究念力转机的旋转方向提供了有效的理论依据。

The force-frequency,azimuthal angle and structure characteristics of wood are three main parameters that affect the rotation of the mechanical,wooden toy Gee-Haw Whammy Diddle.Take orthotropic wood as the object of the research,it adopt to the theory of polarization state and shear-wave characteristics in orthotropic material.Here we predominantly analyze the relationship between force-frequency,azimuthal angle and the rotation of Gee-Haw Whammy Diddle.And it finds out the corresponding relationship between the three parameters and clockwise rotation,counterclockwise rotation and rotation direction sudden change.We provide theory useful evidence for the research on the rotation direction of Gee-Haw Whammy Diddle.
