This paper analyzes from the theories and engineering examples to review rationality of the different torsion effect indexes, such as relative torsion effectθr/u, shear force ratioλbetween torsion and translation, eccentric angle of torsion.

本文從理論分析和算例考證兩個方面，考查相對扭轉效應θr／u、扭轉與平動引起的剪力比值λ和樓層偏心扭轉角α等不同扭轉效應指標的合理性，研究不同指標的影響因素及它們之間的內在聯(lián)系。

The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.
