A. The short answer, yes and yes.
Now the long answer:
- msmac3D, which is based on the hvosm (combined with smac program) has been used extensively in roadway/roadside design evaluations.
- 1992 "Simulation Models of Vehicle Dynamics", April 1992, Transportation Research Board Circular "Beyond the Green Book".
- 2016: Rollover Analysis: minimum speeds and roll velocity approximation
- 2017: Jaguar E-Pace Rollover Stunt Designed by McHenry with msmac3D
- DEMO Toyoyta PU Roll with 2 speed overlayed in single simulation
- Inputs can be easily approximated and many vehicles in the literature have been measured by (and custom vehicles can be measured by)
- This is not a vehicle dynamics simulation program like CarSim or Dynasim or other nearly finite element type simulation programs which can take weeks to build a model from the ground up having to define each and every component in minute detail.
They are great tools but more for the design process of vehicles.
Vehicle dynamics can be evaluated for example when reconstructing a crash where a vehicle rolls over:
- Once you have matched the evidence you can then evaluate 'what if' type scenarios like:
- what if a vehicle was traveling faster/slower (see video of Toyota Pickup rollover above)
- what if a vehicle had a higher/lower center of gravity height
