Dynamics simulation analysis of protal crane boom system based on Adams

At present, the design of port machinery is mainly relied on the method of static design. It sometimes makes the design unprecise and unreasonable. On the basis of vitual prototype technology, this paper takes adventage of Solidworks to build a boom system model of the 40t/33m protal crane. Then inport the model into Adams for the dynamics simulation analysis. At last, we get the variation curves of several hinge-forces(take hinge-forces for a example because it is important in the crane design and complex and unprecise by the former methods) in luffing process. From the curves we obtain the maximum values and in which radius and situation the maximum value occurs.
