项目摘要

The requested funding for the proposed NSERC Engage project will allow the principal investigator, theindustrial partner (Meridian Lightweight Technologies), and Highly Qualified Personnel to investigate anddevelop engineering models of the self-piercing riveting (SPR) system to join Magnesium components to otherMagnesium components or dissimilar metals. This collaborative investigation is necessary due to challengesand lack of success which the industrial partner has had in achieving SPR for Magnesium components.Investigations will be completed, in a collaborative effort between the academic research team and theindustrial partner, to experimentally assess the mechanical material behaviour of base SPR materials.Additionally, in a similar approach, efforts will be undertaken to investigate deformation and mechanicalbehaviour of the SPR components during the riveting process.Information from the experimental portion of this project will be used to develop and validate finite elementmodels of the SPR system. This model will then be further used by the academic research team to exploredesign modifications to improve and enhance the joining of components, specifically components involvingMagnesium alloys, using the SPR method.It is anticipated that the proposed NSERC Engage project will result in the development of information whichwill allow the industrial partner to implement a SPR into challenging lightweight materials, potentiallyresulting in Meridian Lightweight Technologies becoming a world leader in joining of lightweight materials fornumerous practical applications.

拟议的NSERC Engage项目所要求的资金将允许主要研究者、工业合作伙伴（Meridian Lightweight Technologies）和高素质人员研究和开发自冲铆接（SPR）系统的工程模型，以将镁部件连接到其他镁部件或异种金属。由于工业合作伙伴在实现镁部件SPR方面面临的挑战和缺乏成功，因此有必要进行这项合作调查。学术研究团队和工业合作伙伴将共同努力完成调查，以实验评估基础SPR材料的机械材料行为。此外，在类似的方法中，在铆接过程中，将努力研究SPR部件的变形和力学行为。2从该项目实验部分获得的信息将用于开发和验证SPR系统的有限元模型。然后，学术研究团队将进一步使用该模型来探索重新设计修改，以改善和增强使用SPR方法的组件，特别是涉及镁合金的组件的连接。预计拟议的NSERC Engage项目将导致信息的开发，这将允许工业合作伙伴将SPR实施到具有挑战性的轻质材料中，可能导致子午线轻量化技术成为世界领先的轻质材料加入众多的实际应用。
