【Abstract】 By analyzing the deficiency of operation training system of gantry crane, this article presented the necessity of constructing a computer simulation system. The geometry model was made by constructing object surface. The physical characters were introduced, object move trace was analyzed, and matrix of horizontal movement and turning movement were calculated. Geometry matrix and movement matrix were united to stimulate object movement. The modeling scheme of this simulation system was completed by mutual combination of physical model and geometry model. The whole system framework, the software and methods for realizing the modeling scheme were introduced with the description of its prospect.更多还原
