通过调整包角改进电梯曳引条件的案例分析

A Case Study on Elevator Traction Improvement by Angle of Wrap

定义了一个可以综合反映电梯曳引条件的曳引函数。利用正交分析法定性分析了几个参数对曳引函数的影响程度，并对曳引轮包角的影响因素进行了详细分析。采用该曳引函数对通过调整包角改善曳引条件的一个典型案例进行了分析。

Combining two traction conditions, a traction function was defined. Influences of several parameters on the traction function were analyzed by the orthogonal analysis. Particularly, factors on angle of wrap were discussed. Improving plans of a practical case were analyzed by the traction function.
