Finite Element Analysis of Vertical Stiffness of Air Spring System

  • Received Date: 12 Nov 2005
  • Publish Date: 25 Dec 2006
  • The vertical stiffness problem of an air spring system was formulated for finite element analysis,and the nonlinearity of the material,geometry and state,as well as the air-solid coupling,were analyzed theoretically.Finite element model of an air spring system was established with the commercial software ABAQUS,and the rebar element was used for the cords.The vertical stiffness of the air spring system was calculated,and the effects of air pressure and cord angle on it were analyzed.The results show that the vertical stiffness increases with an increase in air pressure,decreases a little with an increase in cord angle.
