This research focuses on the definition of the guidelines to simulate a sled test which reproduces the ODB Euro NCAP crash test, using LS-DYNA Finite Element code. In addition, the last sections are based on the validation of the model, comparing numerical results with those of an experimental sled test performed with the same equipment in late 2018, and on a sensitivity study on the friction coefficient of a virtual slip ring. Several FE models have been utilized, to represent vehicle body, seats and restraint system with LS-DYNA. The subject of the test is a ten-year-old child dummy (Q-series Q10), placed on a booster seat in the second-row seat of the vehicle.
