| Summary: | As to the strength test of seatbelts anchorages which is a quasi-static problem,through comparative analysis of central difference method（ explicit integration） and Newmark method（ implicit integration） in elastodynamics,this paper used explicit solution method in LS-DYNA to compute the seatbelts FE model of domestic minibuses exported to Australia. Lots of studies were carried out herein on two key parameters: calculation time and load curve,and certain evaluation indexes were selected,to gradually improve simulation results consistency with the real test. The methed can be extended to other quasi-static strength analysis problems and gives some useful conclusions on improving simulation accuracy. |
