Adams acceleration magnitude

Hello,
 
I am simulating an experimental gearbox in Adams. When complaring the gearbox vibrations (accelerations) between the experimental measurements and the Adams requests, there is a huge difference in magnitudes. The units in Adams are in mm, but I always make sure to turn them into m so as to compare them to the experimental measurements. I am using the default Adams solver settings, except from the fact that I use multithreading as PREFERENCES/, NTHREADS = 4.
 
I have also read in the documentation that the I3 integrator (which is the default|) may not calculate the accelerations properly, but this great a difference in magnitude shouldn't be related to that.
 
Are there any other things I should look into that might help mitigate my problem?
 
P.S.
 
I am using flexible bodies (the gearbox included) in order to allow for some flexibility in the model.
 
Thanks,

  • I am not sure what you mean, but I might have not stated my question well. When I say that I changed the units from mm to m, I mean after exporting the request files. To clarify, the units in Adams are in mm, I run the simulation and get a request file containing the accelerations, which I then import to a different sofware for post processing (units change and such)
     
    Sorry if my initial question caused confusion
