论文摘要
制造和组装设计（DFMA）是重型车辆制造过程中的关键设计阶段，涉及优化零件组装过程的顺序和可行性，以降低制造的复杂性和整体成本。现有的工作集中在虚拟环境中进行DFMA以降低制造成本，但是用户不太有能力将虚拟组件的物理特性与实际物理对象进行相关性和比较。因此，开发了一个混合现实（MR）应用程序，以使工程师虚拟地可视化和操纵组装零件，并在其预期的物理环境中进行和计划组装。对工程专业人士和非工程师进行了两次试点评估，以评估软件用于组装计划的有效性。可用性结果表明，该应用程序总体可用（M = 56.1，SD = 7.89），并且参与者感到参与活动的感觉（M = 13.1，SD = 3.3）。工程专业人员将应用视为一种有用且具有成本效益的工具，用于优化其机械装配设计。
Design for Manufacturing and Assembly (DFMA) is a crucial design stage within the heavy vehicle manufacturing process that involves optimising the order and feasibility of the parts assembly process to reduce manufacturing complexity and overall cost. Existing work has focused on conducting DFMA within virtual environments to reduce manufacturing costs, but users are less able to relate and compare physical characteristics of a virtual component with real physical objects. Therefore, a Mixed Reality (MR) application is developed for engineers to visualise and manipulate assembly parts virtually, conduct and plan out an assembly within its intended physical environment. Two pilot evaluations were conducted with both engineering professionals and non-engineers to assess effectiveness of the software for assembly planning. Usability results suggest that the application is overall usable (M=56.1, SD=7.89), and participants felt a sense of involvement in the activity (M=13.1, SD=3.3). Engineering professionals see the application as a useful and cost-effective tool for optimising their mechanical assembly designs.
