The last 2 columns are left/right platform displacements if more than one axle is being tested. Change demo_VEH_SuspensionTestRig to use inputs from a file (driver_inputs = DATA_FILE) and change the vehicle being tested to the MTV (uncomment the line “MTV_STR_Setup setup;”) to see that.
You can test as many axles of a vehicle as you want. If using inputs from a data file, there must be 2 + 2*num_axles columns. If you want to modify another vehicle along these lines, make sure to also include the full set of axles in the json file. --Radu From: [email protected] <[email protected]> On Behalf Of osman cankurtaran Sent: Thursday, August 14, 2025 1:44 PM To: ProjectChrono <[email protected]> Subject: [chrono] Question About ST_inputs.dat Columns in Suspension Test Rig Hi everyone, I’ve been going through the suspension test rig examples and had a quick question regarding the ST_inputs.dat load file. There are no column headers in the file, but from what I can tell: * Column 1 seems to be time * Column 2 is steering input * Column 3 is green platform displacement * Column 4 is red platform displacement However, I couldn’t figure out what columns 5 and 6 represent. If anyone knows what these last two columns are used for, I’d really appreciate the clarification.
