| Abstract: |
| This paper aims to study the effect of vent area and initial buffer time on the buffer performance of a type of airbag under impact load. The HIP bone-airbag-ground finite element model was established by using Mimics software and LS-prepost software. The simulation calculation of the airbag buffer process was carried out by using LS-DYNA software, and the dynamic response results of the model in the buffer process were obtained. The influence of vent area and initial contact time on the cushioning performance of the airbag was discussed by analyzing the changes of force and airbag state in the hip model. Within the range of 0~40 mm2, the maximum peak value of the hip bone model was 1 710 N and the minimum was 15 49 N, and the variation range of the peak value was about 10.4%. When the initial buffer time was changed, the maximum peak value of the hip bone model was 1 769 N and the minimum was 1 644 N, and the variation range of the peak value of the hip bone model was about 7.6%. With the increase of the vent area, the buffer performance of the air bag increases first and then decreases. With the delay of the initial buffering time, the buffering performance of the airbag is firstly improved and then decreased. The buffer characteristics of air bag can be better improved by changing the vent area. |
