摘要:机械臂数字孪生模型的评价过程中首要环节是对机械臂概念设计方案进行评价,评价方法的优劣性直接影响整个机械臂的设计与制造。提出一种基于价值函数的层次分析法,在功能分析和形态学矩阵的基础上构建了混合的方案评价模型。在原有的层次分析法过程中,对两个因素之间的比较采取指标价值函数的方式,提高了层次分析法的客观性。研究机械臂的数字孪生概念域模型,解决了机械臂设计方案的选择与优化的问题;结合专家知识,使选择的方案具有专家水平,提高了其评价的客观性;基于价值函数的层次分析法,开发了机械臂数字孪生概念域评价软件。

Abstract:The first step in the evaluation process of the digital twin model of the robotic arm is to evaluate the conceptual design of the robotic arm. The quality of the evaluation method directly affects the design and manufacturing effects of the entire robotic arm. An analytic hierarchy process based on value function is proposed, and a mixed scheme evaluation model is constructed on the basis of functional analysis and morphological matrix. In the original process of analytic hierarchy process, the way of index value function is adopted to compare the two factors, which improves the objectivity of analytic hierarchy process. The research on the digital twin conceptual domain model of the robotic arm solves the problem of selecting and optimizing the design of the robotic arm; the introduction of expert knowledge improves the objectivity of its evaluation; with the analytic hierarchy process based on the value function, the conceptual domain evaluation software of the digital twin of the robotic arm is developed.
Key words:digital twin;conceptual domain design;morphological matrix;analytic hierarchy process
