Turning at full speed the presumption modulo of the projection status information by the blasting machine and the presumption device of projection status information, and the presumption program

摘要

PROBLEM TO BE SOLVED: To provide an estimating method for projection state information by a blast device, reducing the operation cost and time required for pinpointing various conditions for obtaining a predetermined projection state information.;SOLUTION: In the blast device, the projecting state information of the projection material is estimated using an analysis model in which released projection material repeatedly collides with a rotary blade. The estimating method includes processes of: inputting an initial condition including release information of projection material and information on the projection material to the blade; storing the initial condition; a process of computing the position of each projection material, and speed and direction of the projection material after collision with the blade; and estimating predetermined projection state information based on the computing result.;COPYRIGHT: (C)2007,JPO&INPIT
