- Abstract
- In this study, analysis was conducted using the MADYMO program, and a test and comparative analysis were performed to find the plan area of the D-ring point installed in the C-filler of sports utility vehicles(SUVs). The seatbelt that was used in this study was the ELR type. A SELD test was conducted according to the ECE R16 regulation, and the reliability of the model was confirmed by conducting comparative analysis with the MADYMO analysis model. Then an area that could be planned was set up, and simulation was performed at 5 mm intervals to find the area in which the seatbelt webbing would not deviate from the shoulder, and to check the movement of the chest. As a result, the area of the D-ring point that met the regulation was found. When the D-ring moved 5 mm in the X-axis direction, the movement of the dummy's chest changed by about 1.30 mm; when it moved by 5 mm in the Y-axis direction, the chest movement changed by about 1.1 mm; and when it moved by 5 mm in the Z-axis direction, the chest movement changed by about 0.45 mm. It is expected that the results of this study can be utilized as a reference by seatbelt designers for planning purposes. Copyright © 2018 KSAE / 152-11.
