Safety harness design for different load cases

安全带是娱乐和工业环境中安全设备的必要组成部分。虽然它们的主要目的是为身体提供负荷，但这种负荷的不适当分布会导致不适和长期的肌肉骨骼损伤。Arcteryx是一家位于不列颠哥伦比亚省的公司，该公司拥有专利技术，可以将负载分布在单个安全带上，并提高休闲攀岩安全带的用户舒适度。为了扩展到其他线束市场，并保持其对安全性和舒适性的高标准，Arcteryx需要更多关于具有多个负载路径的线束中线束带之间负载分布的信息。拟议的研究项目将有助于设计在身体上的多个带子之间均匀分配负载的线束。这将通过完成两项任务来实现：1)开发一个数学模型，以确定皮带材料特性和均匀分配负载的线束几何形状；2)线束设计原型，并在设计用于在一系列条件下施加负载的机器人中实验测量负载分布。虽然安全带主要是为了安全而设计的，但最大限度地提高舒适性确保了合规使用，并最大限度地减少了长期的肌肉骨骼并发症。负载的均匀分布一直是线束设计的目标，但尚未得到证明或量化。该项目将为线束设计提供数学和实验工具，并帮助Arcteryx在安全性和舒适性方面保持全球领先地位。

Harnesses are a necessary component in safety equipment for both recreational and industrial settings. While their primary purpose is to provide loads to the body, an improper distribution of such loads can lead to discomfort and long-term musculoskeletal injury. Arcteryx, a company based in British Columbia, has patented technologies to distribute loads in a single harness strap, and enhance user comfort in recreational climbing harnesses. To expand to other harness markets and maintain their high standards for safety and comfort, Arcteryx requires more information on the load distributions between harness straps in a harness with multiple load paths onto the body. The proposed research project will aid in design of harnesses that evenly distribute loads between multiple straps on the body. This will be achieved by completing two tasks: 1) developing a mathematical model to determine strap material properties and harness geometry that evenly distributes loads and 2) prototyping the harness design and measuring the load distributions experimentally in a robot designed to apply loads in a range of conditions. While harnesses are primarily designed for safety, maximizing comfort ensures compliant use and minimizes long-term musculoskeletal complications. Even distribution of loads has long been the goal in harness design but has not yet been demonstrated or quantified. This project will provide mathematical and experimental tools for harness design, and help Arcteryx remain a global leader in harnesses manufactured for both safety and comfort.
