A staircase was developed to record ground reactions during stair climbing at different slopes (inclinations). Each step is instrumented with six strain-gauge-based force transducers which allow the measurement of three-dimensional ground reaction force and moment as well as the centre of pressure (COP) location. A specific sensor arrangement permits accurate recording, especially of the COP location. The overall design of the staircase and details of a single instrumented step are presented. Static and dynamic characteristics have been evaluated by different experimental procedures. Preliminary results of ground reaction forces are shown.
设计了一种楼梯，用于记录在不同坡度（倾斜度）下爬楼梯时的地面反作用力。每个台阶都配备了六个基于应变片的力传感器，可测量三维地面反作用力和力矩以及压力中心（COP）位置。一种特定的传感器布置允许进行精确记录，尤其是COP位置的记录。介绍了楼梯的整体设计和单个仪器化台阶的细节。通过不同的实验程序对静态和动态特性进行了评估。展示了地面反作用力的初步结果。
