An MBD based framework for relative position accuracy measurement in digital assembly of large-scale component

Abstract

Purpose This paper aims to promote the integration of the relative position accuracy (RPA) measurement and evaluation in digital assembly process by adopting the model-based method. An integrated framework for RPA measurement is proposed based on a model-based definition (MBD) data set. The study also aims to promote the efficiency of inspection planning of RPA measurement by improving the reusability and configurability of the inspection planning. Design/methodology/approach The works have been carried out on three layers. In the data layer, an extended MBD data set is constructed to describe the objects and data for defining RPA measurement items; In definition layer, a model based and hierarchical structure for RPA item definition is constructed to support quick definition for RPA measurement items. In function layer, a toolset consisting three modules is constructed in a sequence from measurement planning to RPA value solving to visualized displaying again. Based on this framework, a prototype system is developed. Findings The paper provides an identified practice of model-based inspection. It suggests that MBD is valuable in promoting both the integration and efficiency of digital inspection. Research limitations/implications The templates and constructed geometry objects given in this paper are still limited in a scenario of aircraft assembly. The integrity and universality of them still need follow-up works. Practical implications The paper includes implications for the model based digital inspection, the digital assembly and the extended application of MBD. Originality/value This paper expands the application of MBD in inspection and fulfils the need to promote the integration and efficiency of digital inspection in large-scale component assembly.

Model-Based Enterprise Approach in the Product Lifecycle Management: State-of-the-Art and Future Research Directions

“…The results obtained from the literature review allowed for the qualitative clustering of the analyzed papers that address the topic of model-based enterprise, including modelbased definition, in relation to the different lifecycle phases (see Figure 2). Most research papers focused on the adoption of model-based enterprise approach, and model-based definition practices, in relation to the design phase [17][18][19][20] and the manufacturing (a.k.a. build) phase [3,20,21,38].…”

“…However, some reflections can be made on the planning and support phases of the product lifecycle, while the disposal phase seems not to have been taken into consideration. Moreover, other Most research papers focused on the adoption of model-based enterprise approach, and model-based definition practices, in relation to the design phase [17][18][19][20] and the manufacturing (a.k.a. build) phase [3,20,21,38].…”

“…Duan, Shen, and Liu [19] also believe that introducing MBD in the design phase could bring valuable benefits to the company. In particular, the authors focus on the design part inherent in component assembly and investigate a solution to facilitate the MBD integration in relative position accuracy (RPA) measurement in order to make the products' parts or components compliant with the design specifications.…”

“…According to [17,19], the use of MBD technology in design and manufacturing processes has improved data integration and made the workload associated with design, manufacturing, and assembly personnel efficient, thus contributing to improved process performance.…”

“…In particular, the focus is on understanding how MBE and MBD support, benefit, and challenge the organizations during the lifecycle phases. Previous research faces these topics mainly for the management of product information during the technical development activities such as the design phase [17][18][19][20] and the manufacturing phase [3,20,21]. These links appear much aligned with the concept of PDM (Product Data Management) that includes systems for the handling of data throughout the whole design, engineering, and development process, also considering the control of workflows [22].…”
