Hello, i'm studying the dynamic behavior of IRB6660-205/1.9 with the method of EMA. However, I have found that my results ( the third-order natural frequency ) are inconsistent with other researches, possibly due to incorrect inertia matrix. Since I lack experimental conditions, I obtained the mass and rotational inertia from CAD files, which do not match the actual results. Is anyone able to provide the inertia parameters?
Thanks!
