From A/Chassis, I am referring Req/1051~43 for Tire Force & Moment data from vehicle data set. When I checked these Lateral Forces at 4 corners during a constant radius, they were shown as sine-wave-like oscillation around zero-value with a sizeable magnitude equivalent to a given slip angles. (same for Fx, except values for z-axis) I believe this is caused from these F&M values are being reported with a global reference marker... not a vehicle-fixed marker like a CG. Any thought on this? And what to do if F&M data is wanted to be reported in vehicle orientation? (No source code of Req/Subroutine is open to public.)
Hi, In the PAC2002 tire model, the force calculations are done within the ISO coordinate system, but in the tire interface the forces are converted to the global coordinate system of the model and applied to the spindle. In Adams Tire, there are some basic request outputs, forces and torques can be requested in ISO or SAE coordinate systems. Please find the attached screenshot for more details.
