supporting mass

But under certain condition, the spindle should be unsteady, this is decided by the relationship of moment of inertia that spindle to each axis of coordinate system, bearings supporting stiffness, revolving speed of spindle and the imbalance mass control, etc.

但在一定条件下，旋转主轴有可能出现不稳定现象，这取决于主轴绕固联坐标系各轴之转动惯量间的关系、轴承支承刚度、主轴旋转速度和不平衡质量控制等因素。

To solve the collaborative scheduling of multi-workstation of printworks or plate making enterprises, a collaborative pattern design model supporting multi-users and multi-processors was proposed. The model offered a solution to complex interaction tasks and complex calculation problems in mass capacity patterns design.
