Intelligent tensioning and cable adjusting system and method for bridge cable structure
The invention relates to the technical field of building construction, and provides an intelligent tensioning and cable adjusting system and method for a bridge cable structure. Numerical control tensioning equipment; a non-contact cable force measuring device; the intelligent control system is used for correcting the finite element model of the bridge cable structure and calculating the target unstressed cable length of the specified cable based on the corrected finite element model; on the basis of the actually measured cable force, the real-time unstressed cable length of the specified cable in the tensioning process is calculated in real time; and on the basis of the actually measured cable force and the real-time unstressed cable length, in combination with the tensioning force and the tensioning elongation value, the cable force of the specified cable is finely adjusted, so that the unstressed cable length of the specified cable reaches the target unstressed cable length. Dynamic digital twinning in the construction process is achieved, and high-precision, high-quality, rapid, efficient and intelligent tension cable adjusting construction of a bridge cable structure is achieved.
本申请涉及建筑施工技术领域，提供了一种桥梁索结构智能张拉调索系统及方法，包括：实体模型重构设备；数控张拉设备；非接触式索力测量设备；智能控制系统，用于修正桥梁索结构的有限元模型，并基于修正后的有限元模型，计算所述指定索的目标无应力索长量；基于所述实测索力，实时计算出所述指定索在张拉过程中的实时无应力索长量；基于所述实测索力和所述实时无应力索长量，结合所述张拉力和张拉伸长值，对所述指定索的索力进行微调，使所述指定索的无应力索长量达到所述目标无应力索长量。本发明实现施工过程动态数字孪生，实现桥梁索结构的高精度高质量、快速高效智能化张拉调索施工。
