Abstract
(EN)
Provided is a movement analysis device for fibers in a resin, the device being capable of, while reducing an increase in calculation amount, analyzing movement of fibers in a resin in which interference between the fibers is taken into consideration. Specifically, in a movement analysis device 100 for fibers 220 in a resin 210, a fiber analysis unit 20 comprises: a resin speed correction unit 25 that corrects a flow speed of the resin 210 at a position corresponding to a joint 221 acquired by a resin speed acquisition unit 22, on the basis of at least one of the density of the fibers 220 at the position corresponding to the joint 221 and the bending degree of the fibers 220; and an analysis unit 26 that analyzes movement of the fibers 220 in the resin 210 on the basis of the flow speed of the rein 210 corrected by the resin speed correction unit 25.

Spécifiquement, dans un dispositif d’analyse de mouvement (100) pour fibres (220) dans une résine (210), une unité d’analyse de fibre (20) comprend : une unité de correction de vitesse de résine (25) qui corrige une vitesse d’écoulement de la résine (210) à une position correspondant à une articulation (221) acquise par une unité d’acquisition de vitesse de la résine (22), en fonction de la densité des fibres (220) à la position correspondant à l’articulation (221) et/ou du degré de flexion des fibres (220) ; et une unité d’analyse (26) qui analyse le mouvement des fibres (220) dans la résine (210) en fonction de la vitesse d’écoulement de la résine (210) corrigée par l’unité de correction de vitesse de la résine (25).
