本文介绍了皇家墨尔本理工大学设计和开发的原始动态实验装置，用于评估滑雪板模拟的雪上性能。动态装备包括两个独立的气缸来复制骑手脚部的运动，以及三个独立的可调节压力气囊，用于通过根据地形配置的变化改变压力来模拟滑雪地形。定制设计的 PLC 控制系统可以模拟常见的滑雪板动作，从不同板倾斜度的转弯，到鼻部或尾部按压、板滑行，以及最后的跳跃性能。 PLC 程序可以修改或重写，以模拟调查感兴趣的各种地形特征。使用综合应变仪系统确定在负载下测试的滑雪板的应力应变特性。本文详细介绍了动态实验装置的设计、装置校准和测试协议。
The paper presents an original dynamic experimental installation that has been designed and developed at RMIT University for the evaluation of snowboard simulated on-snow performance. The dynamic rig comprises two independent pneumatic cylinders to replicate rider foot movement, as well as three independent adjustable pressure airbags used to simulate the snowboarding terrain by varying their pressure according to the change in the terrain configuration. A custom designed, PLC control system allows for the simulation of common snowboard manoeuvres, from turns of varying board inclination, to nose or tail presses, board slides, and finally the performance of jumps. The PLC programs can be modified or re-written to simulate a variety of terrain features of interest to the investigation. Stress-strain characteristics of the snowboard tested under load are determined using a comprehensive strain gauge system. The paper presents in detail the design of the dynamic experimental installation, rig calibration and testing protocols.
