“…The results of the simulation were comparable to the results of the PMHS experiment. MB forensic models available in reconstruction software were often validated by means of comparison of body motion with video data either from dummy crash tests [9,29,[107][108][109] or CCTV (closed-circuit television) recordings [4,13]. The main focus in those studies was on the model's ability to recreate locations where pedestrians or dummies impacted the vehicle.…”

The review paper discusses numerical human body models of pedestrians. The background of current trends in physical and mathematical pedestrian research is presented. Development, validation and areas of application of pedestrian body models are described. The differences between multibody models and finite element models are presented. Accident-based and experimental approaches to validation of the models are discussed. As a novelty, this paper presents an overview of multibody models used in forensic investigations, discusses their usefulness, and differences between their design and the design of more advanced multibody and finite element models. Finally, the most recent trends in human body modelling are discussed, including open-source approaches to model distribution and replacement of physical tests by digital simulations.

<div class="section abstract"><div class="htmlview paragraph">Building upon prior research, this paper compares computer simulations to a previously conducted rollover crash test of a tractor-semitrailer. The effects of torsional stiffness were elucidated during the correlation of simulations to the rollover test. A commercially available vehicle dynamics and reconstruction software was used for the simulation. Unique aspects of the rollover crash test were modeled in the simulation.</div><div class="htmlview paragraph">A tractor-semitrailer quarter-turn rollover crash test conducted by IMMI was reconstructed using impact and vehicle dynamics models within the simulation software HVE (Human, Vehicle & Environment). The SIMON (SImulation MOdel Non-linear) module and the DyMESH (Dynamic MEchanical SHell) module within HVE were used. During the IMMI test, onboard instrumentation recorded acceleration and roll rate data in six degrees of freedom to characterize both tractor and semitrailer dynamics before and during the rollover event. The roll angle and roll rate behavior of the HVE tractor-semitrailer were correlated to the test data by varying the connection torsional stiffness values within HVE. The roll angle and roll rate temporal data from the test showed that the torsionally compliant combination vehicle stored and released mechanical energy. This effect was also observed in the calibrated HVE model. The effects of varying the crush stiffness values, suspension wheel rates, and the tire-to-pavement coefficient of friction were evaluated in the HVE simulations. Roll angle, roll rate, and impact acceleration temporal test data were compared to corresponding data from the HVE simulations. During the rollover test, a 16,460-lb block of ballast became dislodged. This event was comprehended by the HVE simulation and is compared to the test via still video frames. All known tractor-semitrailer rollover crash tests are included in the literature review. A brief review of rollover simulation literature is included in this paper.</div></div>
