Abstract

The construction process of cable structure has the phenomenon of complex process and changeable influencing factors. How to construct the digital coordinated transmission mode of construction information and realize intelligent decision-making and control is still a bottleneck problem restricting the development and practice of intelligent construction. In this study, the characterization and operation method of cable structure intelligent construction unit (ICU) based on digital twin (DT) is proposed. According to the construction forming characteristics of cable structure, the ICU assembly is defined from the perspective of structural components, construction process and control index. The basic unit is divided, and the mechanism of intelligent construction unit is clarified. Based on the efficient construction of human-computer interaction, a DT six-dimensional reference model is established to realize the sensing and integration, calculation and analysis, control and execution of construction information. On this basis, the operation method of ICU of cable structure driven by DT is given from three aspects: optimal operation control, process correlation coupling and process evolution. The efficient turnover of equipment and tooling and fine construction in the whole process of splicing, lifting and tensioning are realized. Taking the construction process of cable truss structure as an example, a DT construction control platform is developed to verify the practicability and effectiveness of the proposed method and technology. The research results show that the establishment of the ICU accurately defines the construction process of the cable structure and significantly improves the construction efficiency. The DT platform developed according to the unit operation mechanism realizes the closed-loop optimization decision of cable structure construction. In the construction process of the cable structure, the collaborative matching of the components and equipment in each process is realized. By comparing the key control indicators, the rationality of the construction is effectively guaranteed.

基于数字孪生的电缆结构智能施工单元的表达与操作方法

索结构施工过程具有过程复杂、影响因素多变的现象。如何构建建筑信息的数字化协同传输模式，实现智能化决策与控制，仍然是制约智能建筑发展与实践的瓶颈问题。本文提出了基于数字孪生（DT）的电缆结构智能施工单元（ICU）的表征和操作方法。根据缆索结构施工成型特点，从结构构件、施工工艺和控制指标三个方面对ICU装配式进行了定义。对基本单元进行了划分，明确了智能施工单元的机理。基于高效构建人机交互，建立DT六维参考模型，实现构建信息的感知与集成、计算与分析、控制与执行。在此基础上，从最优运行控制、过程关联耦合和过程演化三个方面给出了DT驱动下电缆结构ICU的运行方法。实现了拼接、吊装、张紧全过程设备工装的高效周转和精细施工。以索桁架结构施工过程为例，开发了DT施工控制平台，验证了所提方法和技术的实用性和有效性。研究结果表明，ICU的建立准确界定了索结构的施工过程，显著提高了施工效率。根据单元运行机理开发的DT平台实现了索结构施工的闭环优化决策。在索结构施工过程中，实现了各工序构件和设备的协同匹配。通过对关键控制指标的比较，有效地保证了施工的合理性。

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
