Experimental study on dynamic characteristics of grillage beam floor under harmonic load
Taking the abnormal vibration problem of the grillage beam floor of a certain industrial workshop in the operation of large power equipment as an example,two kinds of vibration reduction and reinforcement schemes of increasing the height of the grillage beam and increasing the thickness of the floor were proposed.Through the scale model test,the vibration reduction effects of different reinforcement schemes of the grillage beam floor structure under the action of harmonic load were studied.The results of scale model test were verified by numerical simulation of finite element software ABAQUS.The results show that both reinforcement schemes can reduce the vertical vibration of the floor structure,and the effect of increasing the height of the grillage beam is more significant than that of increasing the thickness of the floor.
