Abstract:Taking a pool track system as the research object, considering the influence of the bearing on the natural frequen-cy of the track, finite element models are established by using 3D deformable body unit, 3D deformable shell element and 3D de-formable beam element. The first order natural frequency of the track system is calculated based on eigenvalue method. To find outthe law, the evaluation of the vibration characteristics of the track is compared. The characteristics of different methods and thechoice of different methods in engineering are pointed out. By summarizing the conclusions that can guide the design, It aims, toprovide reference guidance for the calculation of track vibration characteristics and design of similar platform in the future.
