2、In this paper, the pnnciple and 3tep3 of finite element method is dexnbed Making use of emulation module of IDEAS of finite element, the strength analysis to cover plate has been done. Based on working condition of cover plate whose geometric model is smiphfied properly and the finite element model

3、is established Thiough such operation as setting up boundary conditions, meshing and solving, the princip.e stress and displacement distnbuuon is obtained This method provides mechanics evidence on structure design of cover plate At the same time, an effective method is also presented to strength an
