Recently, governments around the world are seeking to reduce pedestrian mortality by strengthening pedestrian safety regulations such as Euro-NCAP (European New Car Assessment Program). In 2015, the Euro-NCAP revised the upper leg assessment for the upper legform to WAD (Wrap Around Distance) 775 mm test. The methods and procedures of the revised upper legform to WAD 775 mm test are analyzed and evaluated. Experimental tests are carried out to comprehend the test procedures, and the aspects to be supplemented are observed. A car-to-human model simulation, which reproduces the pedestrian accident, is performed, and the data on the thigh and femur are computed. It is assumed that the car-to-human simulation can represent a real accident. Comparison is conducted between the results of the Euro-NCAP test and the car-to-human simulation, and the problems of the Euro-NCAP test are identified. The car-to-upper legform simulation is carried out to improve the costly repeated Euro-NCAP tests. Also, it is shown that the newly proposed car-to-upper legform simulation can be used to follow the path of the car-to-human model simulation. The upper legform to WAD 775 mm test is discussed based on the results of the experimental tests and the simulations.

最近，世界各地的政府都在寻求通过加强行人安全法规（例如Euro-NCAP（欧洲新车评估计划））来降低行人死亡率。2015年，Euro-NCAP将大腿形态的大腿评估修改为775毫米WAD（环绕距离）测试。分析并评估了上肢形态经WAD 775毫米测试的方法和程序。进行实验测试以理解测试程序，并观察要补充的方面。进行了人与人之间的模型仿真，再现了行人的事故，并计算了大腿和股骨的数据。假设从汽车到人的模拟可以代表真正的事故。比较了Euro-NCAP测试结果和汽车对人的仿真结果，并确定了Euro-NCAP测试的问题。进行了从上到下的腿部模拟，以改善昂贵的重复Euro-NCAP测试。另外，还表明，新提出的从汽车到上肢的腿部仿真可以用来遵循从汽车到人的模型仿真的路径。基于实验测试和模拟的结果，讨论了WAD 775 mm测试的大腿形。
