| 现代工程中,柔索结构的应用日益广泛，简单的理论分析难以满足复杂工程的需要，柔索静动态空间构形与张力测试技术对柔索理论研究和工程应用具有重要的意义，而目前尚没有一套完备的测试装置和技术标准。针对上述情况，本文设计并制造了柔索空间构形与张力测试装置，并通过不锈钢圆环链条的静态空间构形和张力测试试验,与悬链线理论的计算结果进行对比,验证测试装置的可靠性与稳定性。试验结果表明：所建立的装置可以满足柔索的空间构形与张力测试的需要，结果准确，精度较好。证明该装置可以为柔索找形、空间构形、张力、运动轨迹和极限状态等柔索力学特性研究提供试验支持。 |

| In modern engineering, the application of flexible cable structure is becoming more and more extensive and complex, and simple theoretical analysis is difficult to meet the needs of complex engineering. The static and dynamic spatial configuration and tension measurement techniques of flexible cables are very significant to study of flexible cable theory and engineering application, but nowadays there is not a complete set of testing devices and technical standards. In order to solve this problem, space configuration and tension testing device of flexible cable was developed in authors' laboratory. The static spatial configuration and tension test of stainless steel ring chain are compared with the calculation results of catenary theory to verify the reliability and stability of the testing device. Experimental results show that the device is able to meet the requirement of space configuration and tension test of cable. The results are accurate and the accuracy is very well. It can be proved that the device can provide experimental support for cable shape-finding, space configuration, tension, trajectory planning, limit state and the other cable mechanical characteristics. |
