The authors developed and elaborated on a new method to release ski bindings by utilizing an industrial robot to simulate release movement showing a spatial repeatability of ± 0.06 mm. The parametric programming of the release parameters gave free control while executing repeatable release tests. A series of different motion patterns were performed, on the one hand, to test the applicability of the setup to the simulation of motion patterns and, on the other, to check for the impact of the ski deformations like ski deflections within the range of -5 mm to -85 mm, on the safety bindings' release forces. As certain falling mechanisms are related to knee injury, which is the most common severe injury in alpine skiing, this testing method can be used to develop related displacement movements in future. This movements do not necessarily accord with the directional release mechanics of safety ski bindings. The authors specify the developed testing apparatus as device for force measurements in 3D with an accuracy of ± 0.5% in boot-sole-plane. The intention behind this development is to enable faster, more versatile and adaptive testing procedures in R&D.
作者开发并详细阐述了一种新方法，即利用工业机器人模拟释放动作来松开滑雪板固定器，该动作的空间重复性为±0.06毫米。释放参数的参数化编程在执行可重复的释放测试时提供了自由控制。一方面执行了一系列不同的运动模式，以测试该设置对运动模式模拟的适用性，另一方面检查在-5毫米至-85毫米范围内的滑雪板变形（如滑雪板挠度）对安全固定器释放力的影响。由于某些跌倒机制与膝关节损伤有关，而膝关节损伤是高山滑雪中最常见的严重损伤，这种测试方法可用于未来开发相关的位移动作。这些动作不一定符合安全滑雪板固定器的定向释放力学原理。作者将开发的测试设备指定为用于三维力测量的装置，在靴底平面内的精度为±0.5%。这一开发背后的意图是在研发中实现更快、更通用和自适应的测试程序。
