本研究主要针对运动场地表面之二维变形行为。通常进行冲击衰减测试和摩擦测试，以分别评估运动场表面的垂直和水平特性。虽然在人类活动中经常观察到斜向冲击，但这些试验仅处理垂直冲击试验。为此，研制了二维冲击试验装置，用于检测运动表面的二维性能。在以前的研究中，我们评估了二维冲击衰减性能的运动表面的VFR（垂直力减少）和HFR（水平力减少）的值。此外，在这项研究中，我们评估了垂直和水平位移的二维冲击试验与高速视频分析。
This study focused on two-dimensional deformation behavior of sports surfaces. Shock attenuation tests and friction tests are generally performed to assess the vertical and horizontal properties of the sports surfaces, respectively. Although the diagonal impacts are often observed in human activities, these tests treat only the vertical impact test. Therefore two-dimensional impact test device were developed for examining the two-dimensional properties of sport surfaces. In previous studies, we evaluated two-dimensional shock attenuation properties of sports surfaces with the VFR (Vertical Force Reduction) and HFR (Horizontal Force Reduction) values. Additionally, we evaluated vertical and horizontal displacement by two-dimensional impact tests with high-speed video analysis in this study.
