“…16, 17 and 18) and on the process of generation of a hazard that the driver would be struck on his/her side was examined. At present, the research on the influence of the side impact speed on the generation of injuries is often analyzed [36][37][38], e.g. from the point of view of the assessment of risk in road accidents.…”

Kinematics of the motorcar body side deformation process during front-to-side vehicle collision and the emergence of a hazard to car occupants

The kinematics of the process of deformation of the motorcar body side in the culminating phase of a front-to-side vehicle collision has been examined as a possible basis for analyzing and modeling the process of emergence of a hazard to car occupants during a road accident. The course of such accidents has a complex nature and their models are necessarily based on the approximation of non-linear elastoplastic characteristics of impact processes, especially during the transition from the compression phase to the restitution phase of the deformation process. For such characteristics to be obtained, a lot of experimental tests have to be carried out. This paper addresses the short-duration processes with a high degree of complexity.A front-to-side motorcar collision model has been prepared, which made it possible to analyze the process of deformation of the car body side and the emergence of a hazard and injuries to car occupants. The results of calculation of the deformation rate and range in various car body zones, velocity of the test dummy placed on driver’s seat and velocity of possible dummy’s impact against the car body side being deformed may be taken as a basis for designing effective occupant protection systems. The kinematics of the phase of vehicle contact and deformation process was modeled with taking into account results of experimental tests, including the curves characterizing the largely non-linear processes that are decisive for the deformation of the car body side. The deformation processes analyzed on these grounds showed at the same time the range of penetration of the deformed body part into the car interior, which causes a hazard to vehicle occupants. The calculation results have shown e.g. that the car body side is deformed to a depth of 0.2 m as quickly as within 0.02–0.03 s. At such a car body side deformation range, the car body part being deformed hits occupant’s body in his/her hips and pelvis area with a velocity of about 6 m/s.

“…the shoulder and ribcage (Compigne et al 2004), and to the interaction between the arm and the ribcage (Kemper et al 2008;Lessley et al 2010). In particular, attempts were made to identify how the arm position affected the response of the impacted subject and the injury outcomes (Cesari et al 1981;Kemper et al 2008), and the link between shoulder dislocation and the occurrence of subsequent rib fractures (Lessley et al 2010;Donlon et al 2015). These studies were all based on experimental work that involved post-mortem human subjects (PMHS), and provided valuable insight about injury mechanisms in side impacts.…”

“…The development of advanced methods for 3D kinematics measurement during PMHS tests has allowed researchers to describe the PMHS impact response in greater detail. A recent study by Donlon et al (2015) provides a new data set that could be used to further describe the ribcage kinematics in side impact: 3D kinematic animations (3DKA) from side impact tests performed with PMHS were created by combining the 3D kinematics data of specific bones recorded by a markertracking system with the 3D reconstruction of these bones' geometry from medical images. In particular, the trajectory of several vertebrae and of the sternum was reported in Donlon et al (2015).…”

“…Therefore, the goal of the current study was to provide biofidelity assessment targets for the ribcage skeletal kinematics in low-speed side impacts with a rigid wall. Donlon et al (2015) published the 3DKA for three tests where male PMHS were impacted by a rigid wall traveling at 15 km/h. Each subject was installed in a rigid seat and held in position by a system of tethers that were released a few milliseconds prior to the impact (Lessley et al 2010).…”

This study provides both qualitative and quantitative information for the ribcage skeletal kinematics in side impact. This data set provides the information required to better evaluate computational models of the thorax for side impact simulations. The corridors developed in this study provide new biofidelity targets for the impact response of the ribcage. This study contributes to augmenting the state of knowledge of the human chest deformation in side impact to better characterize the rib fracture mechanisms.

Validation of Shoulder Response of Human Body Finite-Element Model (GHBMC) Under Whole Body Lateral Impact Condition

et al. 2016

In previous shoulder impact studies, the 50th-percentile male GHBMC human body finite-element model was shown to have good biofidelity regarding impact force, but under-predicted shoulder deflection by 80% compared to those observed in the experiment. The goal of this study was to validate the response of the GHBMC M50 model by focusing on three-dimensional shoulder kinematics under a whole-body lateral impact condition. Five modifications, focused on material properties and modeling techniques, were introduced into the model and a supplementary sensitivity analysis was done to determine the influence of each modification to the biomechanical response of the body. The modified model predicted substantially improved shoulder response and peak shoulder deflection within 10% of the observed experimental data, and showed good correlation in the scapula kinematics on sagittal and transverse planes. The improvement in the biofidelity of the shoulder region was mainly due to the modifications of material properties of muscle, the acromioclavicular joint, and the attachment region between the pectoralis major and ribs. Predictions of rib fracture and chest deflection were also improved because of these modifications.
