【摘要】 影响塔式起重机稳定性和使用寿命的因素主要包括强度和振动频率。文章从有限元的基础理论出发,利用ANSYS软件,对塔式起重机进行静力学分析,获得了其应力应变结果,比较了三种典型的工况,从而得到危险位置和变形情况,并对塔式起重机进行模态分析,计算出前5阶模态和振型,为其他动力学响应提供依据。更多还原

【Abstract】 With the foundation of the construction scale unceasingly expands,the tower crane used more widely.This paper from the basic theory of finite element method,the crane for statics analysis,compare three kinds of typical working condition,and installing conduct modal analysis,calculates the first five modes and vibration mode,to provide a basis for other dynamic response.更多还原
