Supporting data "Stick-Slip in a Stack: How Slip Dissonance Reveals Aging" - experiments

Content: - experimental data of the total pulling force F(t).- experimental data of the absolute positions of the slabs x_i(t), from image analysis. Description:- each folder n#, with #=[1..5] contains the data for n=# active frictional interfaces. - For each n#, 10 experimental runs are done, each marked by n#_run*, with *=[1..10]. - Each run*, contains two .txt files: - n#_run*_Force, a two tab-separated columns matrix. First column is the time [in seconds], the second the corresponding force F [in Newton]. - n#_run*_Positions, a 7 tab-separated columns matrix. First column is the picture time (synchronized with the force, in seconds), the next 6 columns are the lateral positions x_i of the layers [in mm], with i=[0..5] increasing from left to right. The layer i=0 is the base plate, whose position is fixed. Regardless of n#, all the plates are present in the stack, but only the plates [1..#] are connected to the lever by springs.内容： - 总拉力F(t)的实验数据。 - 通过图像分析得到的板状物绝对位置x_i(t)的实验数据。 说明： - 每个名为n#（其中#取值范围为1~5）的文件夹，存储对应n=#个主动摩擦界面的实验数据。 - 针对每个n#文件夹，共开展10组实验，每组实验以n#_run*命名，其中*取值范围为1~10。 - 每组run*包含两个制表符分隔的文本文件（.txt）： - n#_run*_Force：为两列制表符分隔的矩阵文件。第一列为时间（单位：秒），第二列为对应拉力F（单位：牛顿）。 - n#_run*_Positions：为七列制表符分隔的矩阵文件。第一列为图像采集时间（与拉力数据同步，单位：秒）；后续六列为各层的横向位置x_i（单位：毫米），其中i取值范围为0~5，序号从左到右递增。其中i=0的层为底板，其位置固定。无论n#取何值，堆叠中均包含所有板状物，但仅编号为1~#的板通过弹簧与杠杆相连。
