摘要: 针对液压机械臂数字孪生技术研究中存在的建模领域单一以及孪生模型更新困难等问题,基于数字孪生五维模型理论,提出了一种液压机械臂数字孪生建模方法。构建了包含物理实体、虚拟模型、孪生数据、应用服务与连接等模块的数字孪生模型总体框架,重点研究了基于面向对象、多领域统一和增量式建模思想的虚拟模型建模方法,实现了多领域耦合、孪生模型动态更新的功能。实验结果表明,液压机械臂数字孪生建模方法具有较高的实时性和可更新性,为液压机械臂数字孪生建模提供了新思路。

Abstract: Aiming at the single modeling domain and the difficulty of updating the twin model in the research of Hydraulic Manipulator digital twin technology,a hydraulic manipulator digital twin modeling method is proposed based on the theory of digital twin five-dimensional model. The overall digital twin framework containing physical entities,virtual models,twin data,application services and connections and other modules is constructed,focusing on the virtual model modeling method based on object-oriented,multi-domain unification and incremental modeling ideas,which realizes the function of multi-domain coupling and dynamic updating of the twin model. The experimental results show that the proposed digital twin modeling method for the hydraulic manipulator has high real-time and updatability,which provides a new idea for digital twin modeling of hydraulic machinery.

Key words: hydraulic manipulator, digital twin, five-dimensional model, multi-domain modeling, real-time interactivity
