Modeling and Validation of Moving Deformable Barrier Model with Taper Section Beam Element

摘要

To improve the precision of side impact simulation, MDB model with taper section beam element was established and validated under the GB20071-2006 regulation. The MDB model was used to simulate a side impact test with a production car. The velocities of five key points on the B pillar and the door were outputted and compared with the test data. Numerical results show that the MDB model which based on taper section beam element can meet the requirements of the regulation and is in line with the test data, thus getting a higher accuracy and better simulation application value.
