Tests used to validate models:
- Pendulum testing at BMW testing facility.
- SFI 38.1 sled testing
- SABS Sled Testing
- Leatt®-Lab physical testing
- Research Papers – External
- Other published test results
Typical simulation parameters:
- Contact definitions
- Friction constants
- Material stiffness
- Joint properties
Able to have iterative test runs - decrease cost or time of physical testing and also to simulate real accidents.
Simulation of BMW pendulum tests (conducted at Munich University, Germany) at Leatt®-Lab using MSC. ADAMS LifeMOD™
Good correlation of bending moments (44 Nm vs. 38 Nm peaks) in simulation and physical test validating the simulation model.
Simulation of SFI 38.1 sled test (conducted at Delphi Test Centre, Vandalia, Ohio, USA) using the same H-III 50th percentile ATD as in the pendulum simulation.
70 G impulse over a 60 msec duration, simulating a frontal impact at about 200 mph in a typical NASCAR crash.
Good correlation of upper neck bending moment further validates the model.
In addition Nij values were within 0.2 of each other for the simulation model and the sled test, showing a deviation of less than 3.5 %, subsequently validating the model.
