The Oasys LS-Dyna Environment introduces a new side-impact barrier shell model specifically designed for the China NCAP Protocol. The SC-MDB C-NCAP follows the specifications outlined in the C-NCAP Management Rules (2024 edition) and will be used in the 2024 China New Car Assessment Program (C-NCAP) for its side-impact testing protocol.
The SC-MDB barrier’s six honeycomb blocks have been meticulously validated to comply with C-NCAP SC-MDB specifications. This validation process involved calibrating the LS-Dyna model using simulation results from a 40km/h dynamic impact against a rigid wall. During this test, the barrier, mounted on a trolley, hits a rigid wall and the force-deflection curves generated from the analyses are compared against the specified corridors.
Ensuring the accuracy and performance of these models, the validation work has been conducted across multiple MPP versions of LS-Dyna, including R11.2.2, R13.1.0 and the latest R14.1.0. To streamline pre-processing, simplified definitions for encrypted keywords have been included. While LS-Dyna will ignore this data, Oasys Primer (version 11 onward) will read it to prevent errors during model checking and manipulation.
