As augmented and virtual reality technology is revolutionising the way products are designed and tested, many companies are expanding the range of use cases across their organisations. After 10 years using Virtual Reality (VR) & Augmented Reality (AR) technology during the life cycle of fusion components, the CEA IRFM has improved its skills developing immersive visualisation scenes for the WEST tokamak [, ] project and several ITER Site Support Agreement such as Magnet Infrastructure Facilities for ITER (MIFI) and Test Blanket Module System (TBM) . Data preparation process has been optimized, reducing time cost to convert CAD data to an interactive and immersive model. For the WEST Project, VR engineers developed immersive scenes to simulate assembly sequences, to check component introduction using physics and to show 2D temperature data from diagnostics in a 3D environment. For the TBM case, health and safety oriented model environment is developed. Features for team simulated human access and hands on operations for As Low As Reasonably Achievable (ALARA) optimisation process with motion-tracking system and virtual avatars with ventilated protective pressurised suit simulating worker protection in nuclear environment. For MIFI application, a specific assembly tool has been developed for TF coils interface located on the top and at the bottom junction. During a first phase, the development was driven by iterative design loop (CAD modelling analysis and cinematic by using VR simulations). By means of interactive simulations and immersive conditions, the interface connection task was validated against feasibility including accessibility. AR has also been introduced in the process since a physical mock-up has been augmented to consider the constraint environment of TF Coils. For TBM application, on site AR simulation of the port Cell equipment will provide enhanced environment description. Collaborative immersive context, digital twins and combination between AR/VR & physical mock-ups for validation of maintenance since component design phase will constitute challenge for the near future.

融合设计工程的虚拟和增强现实用例

随着增强现实和虚拟现实技术正在彻底改变产品的设计和测试方式，许多公司正在扩大整个组织的用例范围。在聚变组件的生命周期中使用虚拟现实 (VR) 和增强现实 (AR) 技术 10 年后，CEA IRFM 提高了为 WES​​T 托卡马克 [, ] 项目和多项 ITER 站点支持协议开发沉浸式可视化场景的技能作为 ITER (MIFI) 和测试毯模块系统 (TBM) 的磁体基础设施。数据准备流程得到优化，减少了将 CAD 数据转换为交互式沉浸式模型的时间成本。对于 WEST 项目，VR 工程师开发了沉浸式场景来模拟装配序列、使用物理检查组件引入以及在 3D 环境中显示来自诊断的 2D 温度数据。针对 TBM 案例，开发了面向健康和安全的模型环境。团队模拟人员进入和实际操作的功能，通过运动跟踪系统和虚拟化身，模拟核环境中工人的保护，通过运动跟踪系统和虚拟化身，实现合理实现的最低限度（ALARA）优化过程。对于 MIFI 应用，我们为位于顶部和底部连接处的 TF 线圈接口开发了一种特定的组装工具。在第一阶段，开发是由迭代设计循环（CAD 建模分析和使用 VR 模拟的电影）驱动的。通过交互式模拟和沉浸式条件，对接口连接任务的可行性（包括可访问性）进行了验证。在此过程中还引入了 AR，因为增强了物理模型以考虑 TF 线圈的约束环境。对于TBM应用，港口Cell设备的现场AR模拟将提供增强的环境描述。自组件设计阶段以来，协作沉浸式环境、数字孪生以及 AR/VR 和物理模型之间用于验证维护的组合将在不久的将来构成挑战。
