| 摘 要： | 汽车手制动装置中的钢索在装配时必须预紧到一定张力,装配时的张力采用“三点法”原理测量, 普遍认为由于钢索的弯曲应力,使测量值与实际值不符．通过分析钢索张力测量时的实际受力情况,提出非弯曲效应计算模型,与实验数据比较吻合,从理论上解决了钢丝绳张力快速测量的技术问题,并在实际工艺中得到了稳定的结果． |
| 关 键 词： | 钢丝绳 张力 弹性模量 应力 应变 |

| Abstract: | In assembling an automobile, the cable of handbrake must be pre-tightened appropriately. The tension is usually measured and controlled by a technique called "the tri-point method". However, the results obtained do not agree with the actual ones. Generally, people ascribe this discrepancy to bending rigidity of the cable. This paper presents a new calculating model without bending rigidity by means of considering the actual force condition of a cable. Calculated results agree with the actual ones properly and therefore the technical problem of quickly measuring the tension of cables is resolved theoretically. |
| Keywords: | flexible thin cable tension elastic modulus stress strain |
