扭转机构在工作过程中呈现出复杂的几何、运动和力学特性。为了了解整个结构在工作时的受力情况，有必要对扭转结构中钢丝的几何和力学特性进行深入研究。本文以简单直股为研究对象，通过理论分析和有限元模拟的方法，研究了在自由和约束端面两种边界条件下股的力学特性。分析结果表明，在载荷一定的情况下，端面约束转动时，钢绞线的应变和接触应力较大，容易失效。该方法为一般加捻结构的力学特性分析提供了依据。
The twisting structure presents complex geometric,kinematic and mechanical characteristics in the process of work. In order to learn the stress conditions of the whole structure in working, it is necessary to make deep research on the geometric and mechanical characteristics of the wires in twisting structure. Based on the simple straight strand, this paper studied the mechanical characteristics of strand in two boundary conditions, including freedom and restrain end face, through theoretical analysis and simulation method of finite element. The analysis results show that, in the case of certain load, the strain and touched stress of strand are larger and easier to become invalid when the end face restrain is turning. This method provides basis for analysis of mechanical characteristics for general twisting structure.
