Study on Mass Acceleration Distribution for Dynamic Force Analysis

Based on the principle of relative sinusoidal force calibration, this paper studied the axial and radial acceleration distribution of aluminum cylindrical mass with radius of 70mm and height of 30mm through theoretical derivation, experimental test and simulation analysis. Firstly, the acceleration distribution law of each position of the mass was deduced and obtained; Secondly, the acceleration distribution of mass was tested at each characteristic point; Finally, the mass was modeled and simulated to obtain the axial and radial acceleration distribution, and the results were compared with the theoretical and simulation results. In the axial direction, the theoretical, simulation and experimental results are in good agreement; In terms of radial, the simulation and experimental results are in good agreement, which can be used to modify the absolute stiffness assumption in the future.
