摘 要: | 钢丝绳是不少机械的重要组成部分。钢丝绳属挠性体,负荷时不可避免出现弹性伸长,其关键参数弹性模量的取值问题关系到机械设计的精度与安全性。架空索道、缆索起重机等承载索挠度比较大的设备,弹性伸长更是不可忽视。通过综合考虑挠度引起弹性模量和弹性伸长引起弹性模量推导出等效弹性模量。

Study on Elastic Modulus of Wire Rope |
| |
Abstract: | Wire rope is important part of the majority of machinery.Because of flexible object of wire rope,it is inevitable to produce elastic spread under the load,the value of critical parameter elastic modulus relates to the precision and safety in designing of machinery.Elastic spread should not be neglected in the equipment of large skyline defection,such as aerial ropeway and suspension cable crane.The equivalent elastic modulus was deduced by comprehensive considering deflection and elastic modulus. |

Keywords: | wire rope elastic modulus deflection |
