Simulation system for a construction crane and the simulation method thereof

A simulation method for a construction crane system implemented in a simulation system including an input device, a display device, and a processing device having a computation unit, a collision detection unit and a graphic unit, in which a construction crane numerical model built in the construction crane system includes a manipulation crane model and a non-manipulating suspension model, the method comprising the steps of:

• (A) the input device receiving an instruction to produce varying quantities of parameters in position and direction of each of movable parts of the manipulation crane model;
• (B) the processing device accumulating the parameters in position and direction of each of the movable parts of the manipulation crane model;
• (C) the processing device extracting parameters in position and direction of a connection point between the manipulation crane model and the non-manipulating suspension model, and substituting the parameters in position and direction of the connection point into the non-manipulating suspension model;
• (D) the computation unit performing a matrix computation with the parameters of the non-manipulating suspension model to obtain data in position and direction of each part of the non-manipulating suspension model;
• and
• (E) the collision detection unit determining whether a collision will occur based on the parameters in position and direction of each part of the construction crane, if the collision will occur, adding a condition of collision into the construction crane numerical model for computing the data in position and direction of each part of the construction crane.
