摘要
龙门起重机起吊货物,突然离地引起的冲击振动是起重机动力分析的关键之一。以龙门起重机起升过程涉及到的结构动力学理论和相关算法为依据,从起重机起吊过程特征出发,将起吊过程简化为两质量两自由度系统,并确定主要参数,进行瞬时冲击和振动研究。针对龙门起重机冲击振动进行瞬态动力学分析,用ANSYS软件仿真分析龙门起重机起升的运动过程,得出龙门起重机轮轨接触点的动力响应曲线,为龙门起重机的设计提供参考依据。
To gantry cranes,the vibration that caused by lifting goods suddenly is one of the keys to dynamic analysis.In this paper,studying instantaneous shock and vibration based on the theory of structural dynamics and related algorithms,According to the hoisting characteristic in the hoisting process,the structural dynamics theory was used to simplify the hoisting process to a two masses two degrees of freedom system.Doing Transient Dynamic Analysis for shock and vibration,simulating the lifting process of the gantry cranes with ANSYS software,draw the dynamic response curve of the node that wheel-rail contacted,provides a reference for the design of the gantry crane.
