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用于加热和通风的能量损失的主要来源之一。 降温Durabuilt门窗公司是埃德蒙顿的窗户制造商， 开发新产品来解决这个问题。加拿大的所有窗户制造商都必须满足 CSA标准的跨窗压差限制了窗户的移动量、空气损失 和水的侵入。所有新产品在CSA批准之前都经过测试以满足此标准。本研究 该项目将向Durabuilt介绍基于立体视觉的新光学仪器，以确定 在测试期间窗口的三维位移。基于数字图像相关技术， 仪器不仅可以用来确定窗口的位移，而且可以用来确定表面应变 产生的。这是确定当前窗口设计的限制的重要信息， 还为窗口设计的未来方向提供了重要的见解。研究与 开发工作将设计和建造一个优化的成像系统，以满足以下独特的测试要求： 窗户然后，该系统将用于对窗户性能进行初步调查， 强调光学仪器的性能，并提供有关 窗口设计这项工作被视为窗户设计和测试的一个全新方向。

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.
