桩架的起架油缸铰座的分析计算

摘 要 本文系统阐述了桩架的基本组成和用途，桩架立柱的起驾方式，根据理论计算出桩架立柱的铰点力大小，并借助MATLAB软件进行运动仿真，找到了桩架立柱起架过程中起架油缸铰点力的变化情况，运用Solidworks软件建立起架油缸铰座的实体模型，结合ANSYS软件进行接触非线性有限元分析，得出了起架油缸铰座与上平台结构在面与面接触的情况下铰座的应力云图，为桩架立柱的铰点确定和起驾油缸铰座的开发和应用提供了依据。

The Analysis and Calculation of the Oil Cylinder in Raising Pillar Hinged Shaft Pedestal of Pile Frame

The article introduces the basic composition and use of pile frame,the way that pillar of pile Frame is raised in,According to the theory of pile frame calculates pillar the hinge point force size,And by MATLAB software movement simulation,Finds the pile frame pillar rising in the process that oil cylinder hinge point of force how to change,Uses Solidworks software to set up the entity model of oil cylinder in raising pillar hinged shaft pedestal,Combines with ANSYS software nonlinear finite element contact analysis,Concludes surface contact of the stress of the hinged shaft pedestal cloud between oil cylinder in raising pillar hinged shaft pedestal and the platform structure,which gives the pile frame pillar hinge point determination and oil cylinder hinged shaft pedesatal a development and application to provide the basis.
