The application of stereo digital image correlation (DIC) to the performance testing of domestic windows

住宅或建筑物的窗户是供暖和建筑能耗的主要来源之一。 正在降温。DuraBuild Windows&Doors Inc.是一家总部位于埃德蒙顿的窗户制造商，该公司继续 开发解决这一问题的新产品。加拿大的所有窗户制造商都必须符合 CSA标准，用于限制车窗移动和空气损失的压差 和水的进入。在CSA批准之前，所有新产品都要经过测试，以满足这一标准。这项研究 该项目将向Dura推出基于立体视觉的新型光学仪器，以确定 测试过程中窗户的三维位移。基于数字图像相关(DIC)， 仪器不仅可以用来确定窗户的位移，还可以用来确定表面应变 所产生的能量。这是确定当前窗口设计的限制和 还为窗的设计提供了对未来方向的重要洞察。该研究和 开发工作将设计和建造优化的成像系统，以满足独特的测试要求 窗户。然后将使用该系统对窗口性能进行初步调查，以 重点介绍光学仪器的性能，并提供有关 窗户设计。这项工作被视为窗口设计和测试的一个根本新方向。

The windows of a dwelling or building are one of the major sources of energy loss for both heating and cooling. Durabuilt Windows & Doors Inc. is an Edmonton-based manufacturer of windows that continues to develop new products that address this problem. All window manufacturers in Canada are required to meet a CSA standard for pressure differential across the window to limit the amount of window movement, air loss and ingress of water. All new products are tested to meet this standard before CSA approval. This research project will introduce to Durabuilt new optical instrumentation based on stereo vision to determine the three-dimensional displacement of the window during testing. Based on digital image correlation (DIC), the instrumentation can be used to determine not only the displacement of the window but also the surface strains that are generated. This is important information to determine the limitations of a current window design and also provides important insight into future directions for the design of a window. The research and development work will design and build an optimised imaging system for the unique testing requirements of the window. The system will then be used to carry out an initial investigation into window performance to highlight both the performance of the optical instrumentation as well as provide detailed information on the window design. This work is seen as a fundamentally new direction for the design and testing of windows.
