摘要
A method for analyzing movement of objects in a graphic construction simulation system is provided to secure stability about equipment management and improve construction ability in a construction field by linking a physical model with a graphic model for movement of a pulley and rotation of a boom in a tower crane. A physical model type of a crane is established to classify movement of objects into each group(S10). A movement equation is extracted for each physical model type by using Lagrange equation(S12). The movement equation of each model is stored in a file(S14). The file is loaded to a VR(Virtual Reality) simulation device by using a script(S16). The movement of the object is visualized according to work progress by linking with a graphic object in a program of the VR simulation device(S18). The movement equation established by the Lagrange equation is numerically analyzed by using Runge-Kutta analysis.
