  • Information processing apparatus and its control method
    Patent number: 7580815
    Abstract: When the convey behavior of a flexible medium conveyed in a conveying path is analyzed by simulation, a design support apparatus of this invention executes 1) processing for approximating a nip on a model to an actual nip, 2) processing for matching a feature point of a drive chart with a calculation step upon making a numerical calculation for solving a motion of a flexible medium using the drive chart, and 3) processing for reflecting velocity variations due to deformation of a convey roller pair, thus implementing a simulation with high accuracy. When the design support apparatus of this invention is used, even a designer who does not have expert knowledge on simulation can analyze the convey behavior of the flexible medium conveyed in the conveying path with relatively higher accuracy.
