Research In Action
Over the past five years, CIRP engineers have utilized pediatric human body computational models to complement traditional laboratory-based research methods. The 6-Year-Old PIPER human body model was developed by the EU consortium based on MRI/CT scan data with detailed internal organs and skeleton structure from human body data. CIRP scientists then developed additional sized models (18-month-old, 24-month-old, and 36-month-old) to further understand responses on occupants in a crash; we call this virtual autopsy.
The human body model is such a useful research tool because it allows for researchers to understand how the human body responds to crash forces rather than a typical crash test dummy. The human body model also enables us to “look inside” before, during, and after a crash to further help refine safety technologies, education and best practices.
Updating Crash Simulations
Recently, our team utilized computational modeling with the PIPER model to update crash simulations to better understand the responses of 18-month-old and 6-year-old occupants in crashes. In the video with the 18-month-old model, a side-by-side comparison of the child’s response in a 35 mph crash when restrained in a rear-facing child restraint system (CRS) versus a forward-facing CRS is shown.
In the video with the 6-year-old model, a side-by-side comparison of the child’s response in a 35 mph crash when restrained in a belt-positioning booster seat versus lap and shoulder belt is shown. The updated simulations provide entirely new insight into the kinematic responses of the human body. For example, we can now visualize the position of the seat belt (lap/shoulder belt) and if an occupant is restrained over a boney structure.
With CIRP’s research to action to impact model in mind, we have made these simulations available as educational resources on our Injury Research In Action YouTube channel. The videos can be shared via social media, in presentations, or at car seat checks with families to visually demonstrate how differences in child passenger safety practices can impact a child’s injury risk in a crash.
