First system the global static calculation are done respectively for the force displacement, stress and local stress on HSG type hydraulic cylinder; And then strength check is done for the main axial load components under the piston rod of the buckling, stability analysis of components is done; The modal analysis is carried out on the hydraulic cylinder system, through calculating natural frequency of the system can effectively prevent the occurrence of resonance hazard. The proposed method and the analysis results have important reference value for research and development of HSG type hydraulic cylinder.Key words：Finite element; Hydraulic cylinder;Static analysis; Buckling analysis; Modal analysis1 引言液压缸是一种将液压能转变为机械能的、做直线往复运动（或摆动运动）的液压元件，具有结构简单，工作可靠的特...
