Virtual Prototype Modeling Technology of Crawler Crane Based on Theory of Rigid-Flexible Coupling

For the complexity of the system modeling, a method of rigid-flexible coupling modeling is proposed based on some software. The virtual prototype model of 350t crawler crane is established. The simulation environment of Pro/E, Adams and Ansys is integrated in order to combine advantages of all three software, by which the dynamics property of virtual prototype model is analyzed. And the simulation results confirm the feasibility of the virtual prototype in product design.
