Central parts of mechanism of elevating and equilibrating were also processed static, dynamic, flectional analyses with finite element method by using Pro/MECHANICA. In the end, its dynamical model was built and simulated in ADAMS, dynamical responding of its hydraulic elevating part was analyzed, gun muzzle's elevation disturbance in different fire angle and so on were obtained, work performance of mechanism of elevating and equilibrating was more studied.
