Experiment Simulation of Seat Belt and ISOFIX Anchorage for a Commercial Vehicle

摘要

In order to estimate the seat belt anchorage and ISOFIX anchorage system of a commercial vehicle typed M1 whether or not meet the new Regulation GB 14167-2013, a commercial vehicle seat model was established using finite element software LS-DYNA 3D. Based on the model, the anchorage strength of three-point seat belt was carried by experiment simulation and testing analysis, while the anchorage strength of ISOFIX was carried by experiment simulation analysis. The result shows that the simulation data of anchorage of three-point seat belt for commercial vehicle is in good agreement with the physical test, and the simulation model is valuable. While the ISOFIX anchorage has enough strength carried on by the new regulation.
