钢丝绳绷紧张力的力学模型

Mechanical model of wire rope tighten tension

对已有的钢丝绳绷紧张力公式进行了量纲分析,量纲分析结果指出:已有的公式左侧的单位是力,右侧的单位是质量。在合理的物理假设基础上,通过数学和物理推导,给出了钢丝绳绷紧张力公式的正确形式。和已有的公式相比,正确的公式没有重力加速度。在钢丝绳设计计算中,如果使用不常用的计算公式,应对公式核准后再使用。

To analyze the existing wire rope tighten tension formula dimensional, dimensional analysis result points out that the left side of the existing formula unit is force, the right side of the unit is quality-. On the basis of reasonable physical assumptions, through mathematies and physics derivation, the correct form of wire rope tighten tension formul is given. Compared with the existing formula, right formula is no gravity acceleration. In wire rope design and calculation, if uncommonly formula is used, dealing with the formula for approval before using.
