Calculating Static Rollover Threshold Using Automotive Tilt Table Event and MotionSolve
Preface: The automotive Static Rollover Threshold (SRT) refers to the maximum tilt angle at which a vehicle is likely to tip/roll over during a static situation. The SRT can be used to predict the vehicle lateral acceleration in which rollover may occur. Vehicles with a low Static Rollover Threshold (SRT) are at a greater…

Motionview
I am currently trying to learn how to make my own events/roads and tasks for my altair driver in motionview. I got to this page and tried to follow the instructions but whatever I do I get an error and the solver fails (example constant radius with constant velocity event). The first error is about version which i think i…
