A: Yes. First see a couple other threads on the topic:
- msmac3D is a combination of SMAC and HVOSM with all our McHenry extensions and refinements
HVOSM has extensive validations 4 Volume set on HVOSM including Volume 4 - Validation- Note: The majority of the 4 volume reports are simply reprints of a decade of research and development performed and authored by Raymond R McHenry and Calspan, see HVOSM reports on Over 50 years of McHenry Highway Safety Research for original source materials.
- HVOSM-97
- Simulation of Vehicle Dynamics
- 2017 we designed the 2018 Jaguar rollout rollover stunt with msmac3D as further proof of the validity of the msmac3D/hvosm program[/url]
- The Proper Use of Simulation Technology for Collision and Rollover Reconstruction and Highway Safety
- The paper serves as a validation of msmac3D:
- Note the published comparisons of the results of msmac3D with the measured full scale test results wherein we correlate with the time history measurements of roll & pitch on rollover tests and the RICSAC full scale tests (see below) while also matching speeds and impact speed changes.
- A Review of the Development and Validation of Simulation Technology for Vehicular Accident Reconstruction
ALSO, please note:- The msmac2D program has been thoroughly validated and msmac3D runs in 2D mode and produces the same results.
- NOTE: the results of this re-evaluation of the RICSAC tests were reviewed and accepted. One of the reviewers. Terry Day of Engineering Dynamics (who make EDSMAC, HVE, etc) stated PLEASE NOTE:In 2003 we used the corrected DeltaV values to further validate msmac.
- SMAC2003: The Automatic Iteration of SMAC
- In this paper we demonstrated that with automatic iteration/optimization we remove initial speed as an input for SMAC validation.
Why?
If you know the impact speed/answer then you can tweak the inputs until you get a match (as many other 'validation' papers do).
In our 2003 paper we did not use the known impact speeds as an SMAC input!
We started with approximate speeds from CRASH3/momentum solutions and then the program iterated/optimized to obtain a match of rest positions and damage and the results for the impact speed and deltaV (impact speed change) were within 5-10% for all the RICSAC full scale tests and other tests.
- In this paper we demonstrated that with automatic iteration/optimization we remove initial speed as an input for SMAC validation.
These comparisons demonstrate good correlation of the predicted roll, pitch and yaw responses with some rollover and RICSAC full scale test measurements:
