sliding pulley

In order to analysis the cable structures with pulley sliding on the cable, or cable sliding under pulley, a new element was developed.

为了分析索结构中滑轮在悬索上行走及连续长索从滑轮下绕行问题，创建了一种新的单元。

The feeding device is wholly connected with the movable frames in a sliding mode and comprises a material drum, a spiral plate, a pulley and a motor.

上料装置整体和移动架滑动连接，由物料筒、螺旋板、皮带轮和电动机组成。

Sensor supporting bracket are main parts of measuring organ. Sliding supporting axis and pulley actualize the movement function with servomotor drive system.

传感器支架是测量机构的重要辅助部分，滑动支承杆和滑轮配合伺服电机驱动系统实现测量装置的运动功能。

This new three-node element, which is called sliding cable element, can simulate the cable sliding under a pulley by point contact, and it simplifies computations by automatically adjusting the cable segments on each side of the pulley.

被称为滑移索单元的新单元有三个节点，以点接触的形式模拟索从下方绕过滑轮，它可以通过自动调整两侧索段的长度而使单元处于平衡状态，从而简化了计算。
