Abstract

An application operation simulation device including a specification section that specifies positions of nozzles with respect to a spray device and injection shapes of injected materials; an interference point calculation section that performs a working program of a robot including instructions for outputting the injected materials to operate a three-dimensional model of the robot by simulation and calculate interference points between three-dimensional models of the injection shapes and a three-dimensional model of an applied member; an interference number calculation section that calculates the number of interference at each interference point on a surface of the three-dimensional model of the applied member; an application time calculation section that calculates application time from the number of interference; and a display section that displays the color-coded surface of the three-dimensional model.
