Bicycle Steer Torque Magnitude Measurement Dataset
收藏资源简介:
A torque wrench was fixed to the stem of the bicycle fork and two riders performed a set of controlled maneuvers at various speeds. The torque wrench, handlebars and speedometer were recorded from a camera affixed to the bicycle frame. The speed was maintained by an electric hub motor (i.e. no pedaling). The file "data.txt" includes the run number that corresponds to the video number, the rider's estimate of the speed after the run in miles per hour, the maximum reading from the torque needle after the run in inch-lbs, the rider's name, the maneuver, the minimum speed seen on the video footage in miles per hour, the maximum speed seen on the video footage in miles per hour, the maximum torque seen on the video footage in inch-lbs, the minimum torque seen on the video footage in newton-meters, and the rotation sense for each run (+ for clockwise [right turn] and - for counter clockwise [left turn]). There were seven different maneuvers: straight into tracking a half circle (radius = 6 meters and 10 meters), tracking a straight line, straight to a 2 meter lane change, slalom with 3 meter spacing, steady circle tracking (radius = 5 and 10 meters). Details of the experiments and example results can be found in: Moore, J. K., "Human Control of a Bicycle", 2012 http://moorepants.github.io All of the video data is hosted on the Internet Archive: https://archive.org/details/BicycleSteerTorqueExperiment01
将扭矩扳手(torque wrench)固定于自行车前叉立管,由两名骑手以不同车速完成一系列受控操控动作。安装于自行车车架的摄像机将拍摄扭矩扳手、车把与速度计的画面。车速由电动轮毂电机(electric hub motor,无需脚踏蹬行)维持。文件"data.txt"包含以下试验数据:对应视频编号的试验序号、试验后骑手估算的车速(单位:英里每小时)、试验后扭矩指针的最大读数(单位:英寸·磅)、骑手姓名、操控动作类型、视频画面记录的最低车速(单位:英里每小时)、视频画面记录的最高车速(单位:英里每小时)、视频画面记录的最大扭矩(单位:英寸·磅)、视频画面记录的最小扭矩(单位:牛顿·米),以及每次试验的转向方向("+"代表顺时针[右转],"-"代表逆时针[左转])。本次试验共涵盖7种不同操控动作:直行转入半圆轨迹(半径分别为6米与10米)、沿直线轨迹行驶、直行切换至2米车道变更、间距3米的绕桩动作、稳定圆周轨迹行驶(半径分别为5米与10米)。本试验的详细细节与示例结果可参阅:Moore, J.
