An Adaptive Algorithm for Rapid Generation of Seat Belt Mesh Model
In the crash safety simulation of civil aircraft,the occupant seat belts are modeled in CAD before the finite element analysis is performed.However,due to the frequent need to adjust the pose and contact definition of the dummy in simulation analysis,it is much inconvenient to adjust the seat belt model of completed 3D modeling.Owing to the structural characteristics of the shoulder straps of the four-point seat belt in civil aircraft,the common finite element analysis software fails to generate an accurate obstacle avoidance seat belt model quickly.Therefore,an adaptive seat belt model generation algorithm is established based on obstacle information,which can automatically generate the adaptive seat belt model by adding key obstacle crossing points and improve the quality of the model.
