Container Cranes Dynamic Simulation Based On Virtual Prototyping Technology

With the development of computer technology, as a CAE technology, Virtual Prototyping technology has also developed rapidly since the 80's of the 20th century. Using Virtual Prototyping model on computer, engineers can simulate various dynamics working-process and analyze the results of the simulation , then improve the Virtual Prototyping model to make it more reality. Finally, people can replace the traditional physical prototype experiment by simulating the Virtual Prototype digital model.This paper is trying to make a way for introducing the dynamic design concept into large-sized and complicated structure designing of crane. With parameterized modeling, this thesis realizes two kinds of rigid-flexible coupled dynamics hoisting working-process simulations of a shore container crane based on variable speed control.The paper is made up of three parts-theory introducing, modeling and working-process simulation .Theory introducing consists of: Virtual Prototyping Technology theory; Finite Element technique theory; ADAMS flexible body dynamics theory; shore container crane load swing dynamic model theory.Virtual Prototyping Modeling consists of: Building a 3-D model of shore container crane in SolidWorks ; Meshing the 3-D model in ANSYS with APDL ; Exporting the ANSYS's Finite Element model to ADAMS ; Building dispersed steel rope system in ADAMS with macro and define constraints as well as contacts of rigid-flexible coupled system.Working-process simulations consists of: modal analysis of the whole shore container crane model in ANSYS; simulations about two kinds of hoising working-process at shore container crane's out reach with rating load in ADAMS.
