Experimental Testing and Numerical Modeling of Self-Piercing Riveting for Enhanced Lightweight Material Joining

为拟议的NSERC Engage项目申请的资金将使主要研究员、工业合作伙伴(子午线轻型技术公司)和高素质人员能够研究和开发自穿孔铆接(SPR)系统的工程模型，以将镁组件连接到其他镁组件或不同的金属上。这次合作调查是必要的，因为工业伙伴在实现镁组件的SPR方面遇到了挑战和缺乏成功。调查将在学术研究团队和工业合作伙伴的合作下完成，以对基础SPR材料的机械材料行为进行实验评估。此外，将以类似的方法调查SPR组件在铆接过程中的变形和力学行为。本项目实验部分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进行重新设计修改，以改进和增强组件的连接，特别是涉及镁合金的组件的连接。预计拟议的NSERC Engage项目将导致开发信息，使工业合作伙伴能够实施SPR来挑战轻质材料，潜在地使子午线轻质技术成为众多实际应用的轻质材料连接方面的世界领先者。

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.
