摘要
为了得到良好的工作机动性,现代门座起重机大多采用摆动臂架式变幅,其中最典型的是四连杆组合臂架变幅机构。文中运用ADAMS仿真软件,对门座起重机四连杆组合臂架变幅机构进行三维建模以及运动仿真,并完成关于变幅运动过程的位移、速度和加速度曲线分析,较好地解决了门座起重机变幅轨迹问题,为门座起重机四连杆组合臂架系统的设计提供了重要的参考数据。
In order to obtain good maneuverability,most modern portal cranes adopt swing jib luffing mechanism,among which the most typical one is the four-bar combination jib luffing mechanism.In this paper,by using ADAMS simulation software,the three-dimensional modeling and motion simulation of the luffing mechanism of the portal crane’s four-bar combination jib are carried out,and the displacement,velocity and acceleration curves in the luffing process are analyzed,which solves the luffing trajectory of the portal crane well and provides important reference data for the design of the portal crane’s four-bar combination jib system.
