Helmet Impact Multiscale Modeling and Simulation

以更低的成本开发更安全的自行车和摩托车头盔将极大地提高其有效性和使用率，从而避免创伤、身体伤害或生命损失。2000-2016年间，全球每年有超过100万人死于道路交通事故，其中54%是骑自行车、骑摩托车的人和行人，世界卫生组织估计“头部损伤是导致死亡和重大创伤的主要原因”，“使用头盔可以使致命伤害的风险降低42%，头部受伤的风险降低69%”。这些统计数据突显了对更有效、更便宜的头盔的巨大需求和巨大市场潜力的重要性和存在。然而，目前创新受到缺乏准确模拟方法的限制，这需要漫长的测试和高昂的开发成本。由于目前还没有明确的建模方法，魁北克一家专门从事产品设计模拟和优化的工程公司LX Sim寻求与康科迪亚大学进行研究合作，以开发模拟头盔碰撞的建模能力。开发高效和准确的头盔设计建模和仿真技术将使原型制造前的设计迭代次数增加，这将极大地促进创新，并为加拿大的头盔制造商提供最佳设计解决方案。改进的头盔设计将显著减少头部受伤和相关的医疗成本。

Developing safer bicycle and motorcycle bike helmets at reduced cost would greatly increase their effectiveness and usage, thus avoiding trauma, physical injuries or loss of life. With over 1 million road traffic deaths worldwide recorded annually between 2000-2016, out of which 54% represent cyclists, motorcyclists and pedestrians, the World Health Organization estimates that "head injuries are the leading cause of death and major trauma", and that "helmet use can lead to a 42% reduction in the risk of fatal injuries and a 69% reduction in the risk of head injuries" .These statistics highlight the importance and the existence of a great need and huge market potential for more effective and less expensive helmets. However, innovation is currently limited by the lack of accurate simulation methods, which entails lengthy testing and high development costs. Since no well-defined modeling methods exist at present, LX Sim, an engineering company in Quebec specialized in simulation and optimization of product design seeks research collaboration with Concordia University to develop modeling capabilities for simulating helmet impacts. Development of efficient and accurate modeling and simulation techniques for helmet design would allow for an increased number of design iterations before manufacturing of prototypes, which would greatly boost innovation and provide optimum design solutions for helmet manufactures in Canada. Improved helmet design will lead to significant reduction in head injuries and associated health costs.
