Analysis and Evaluation of the Euro-NCAP Upper Legform to WAD 775 mm Test

Abstract

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.
