The upsetting process of cylindrical forging was investigated using finite element method. The influence of conical anvil on deformation rule of metal and distribution of strain and stress was studied using software MSC. Marc. The simulated results indicated that it had a smaller rigid zone and more homogeneous deformation zone in the billet during upsetting process with conical anvil compared with flat anvil. The critical reduction in height which could assure the three dimensional compressive stress states for the upsetting with conical anvil was smaller than that for the flat one.

In this paper, a finite element model of membrane air spring in the vehicle is established, and its vertical stiffness characteristics under a certain inflation pressure are analysed. The result of finite element simulation method is compared with the result of the air spring bench test. The accuracy and reliability of the finite element simulation method in nonlinear analysis of air spring system are verified. In addition, according to the finite element method, the influence of the installation of the air spring limit sleeve on its stiffness is verified.
