China Special Equipment Inspection and Research Institute, Beijing 100013, China Abstract The design of shipbuilding gantry crane is mostly based on static methods, using statistics of similar products and empirical formula, which often means a long cycle, high-cost and low-quality. In this paper, based on the technique of virtual prototype, a virtual prototype model of 300t shipbuilding gantry crane is established by integrating Pro/Engineer with ADAMS, that is, using the three - dimensional solid modeling software Pro/Engineer to establish three-dimensional model of the system, then importing the model to ADAMS and adding corresponding constraints and loads on the components. With the virtual prototype, dynamic simulation of the multi -body system is carried out, including the ru
