【Abstract】 With the safety cable for flexible luffing jib cranes as the research object,dynamic simulation software ADAMS is used in the paper together with a finite element analysis software to develop a rigid-flexible coupling model based on multi-body system dynamics. And simulation helps get THE dynamic behavior of luffing jib under the influence of safety cable as well as pull-up curve of safety cable. Then,the security of the system under different working conditions is analyzed on the basis of jib structure and the ultimate bearing capacity of safety cables.更多还原
