The Stability Analysis of Pulldown Armed Truck Crane
-
摘要: 以某型折臂式随车起重运输车为研究对象,利用ADAMS(Automatic Dynamic Analysis ofMechanical Systems)软件建立了它的虚拟样机模型,并对其回转工作过程进行了运动学仿真,获得了该过程中随车起重运输车的质心变化曲线。再根据力矩平衡原理,采用Matlab(Matrix Laborato-ry)软件绘出该折臂式随车起重运输车不同倾覆线段的最大起重量曲线图,分析其稳定性。分析结果表明:该随车起重运输车在前方和左前方倾翻线的位置,最大起重量小于随车吊的额定起升量,容易发生倾翻。与传统的方法相比,基于ADAMS软件的设计方法更能满足高效、灵活的设计要求。

Abstract: A kind of pulldown armed truck crane was studied in this paper.The virtual prototype model of that was built by ADAMS(Automatic Dynamic Analysis of Mechanical Systems)software and the kinematic simulation of its ratation was done.The centroid curve of the pulldown armed truck crane was obtained.Based on this,the stability of the crane system was analyzed on the theory of trimming moment and the maximum lifting weights on diffenert danger paragraph were drawn by Matlab(Matrix Laboratory) software.The result indicates that the maximum lifting weight on frontage and left-frontage is less than the rated value of the truck crane,which are the dangerous places to overturn.Compared with traditional method,the ADAMS method in this paper can satisfy the design need of efficient,flexible design.-
