本文旨在解决与摩擦测量相关的问题，例如摩擦与以人为中心的评估和实际滑动之间的关系，以及摩擦测量的可重复性如何。对常用的光滑度测量设备进行了调查，并将其特性与第 1 部分中总结的生物力学观察中建议的测试条件进行了比较。设备有效性、可重复性、再现性和可用性问题通过已发表的文献进行了审查。使用所描述的机械测量设备进行摩擦评估通常是有效且可靠的。然而，通过将大多数设备置于生物力学研究中观察到的人体滑倒条件范围内，可以提高其有效性。未来的研究应清楚地描述任何设备的性能限制及其结果，并应考虑设备条件是否反映了这些实际的人类滑倒条件。还需要通过步行实验对更多设备进行验证研究。
This paper seeks to address questions related to friction measurement such as how friction is related to human-centred assessment and actual slipping, and how repeatable friction measurements are. Commonly used devices for slipperiness measurement are surveyed and their characteristics compared with suggested test conditions from biomechanical observations summarized in Part 1. The issues of device validity, repeatability, reproducibility and usability are examined from the published literature. Friction assessment using the mechanical measurement devices described appears generally valid and reliable. However, the validity of most devices could be improved by bringing them within the range of human slipping conditions observed in biomechanical studies. Future studies should clearly describe the performance limitations of any device and its results and should consider whether the device conditions reflect these actual human slipping conditions. There is also a need for validation studies of more devices by walking experiments.
