Further analyses was made on the related rough positioning accuracy of turning accuracy and on the overcoming of rotating inertia of the rotary indexing.
进一步分析了其有关转位精度的粗定位精度与回转分度的转动惯量的克服。

Moment of inertia: turning around its axis of symmetry, object has the character keeping speed and the direction of the axis of rotation not changing.
转动惯性：物体在绕着自己的对称轴转动时，具有保持转速和转动轴方向不变的性质。

Moreover, the article elucidates the influence of various parameters on the dynamic response of the hoist - the damp of elastic coupling, stiffness, each turninginertia of hoist shaft, etc.
