Abstract

This heat exchanger analysis device includes a chronological change acquisition unit, a temperature fluctuation region identification unit, a fluctuation frequency calculation unit, and a fatigue determination unit. The chronological change acquisition unit acquires the chronological change of a metal temperature measured at a measurement point provided to a heat exchanger. The temperature fluctuation region identification unit identifies, from the chronological change, a plurality of temperature fluctuation regions that have a temperature fluctuation range. The fluctuation frequency calculation unit calculates a fluctuation frequency of the metal temperature in a predetermined period on the basis of the plurality of temperature fluctuation regions. The fatigue determination unit determines, on the basis of the fluctuation frequency, whether a heat exchanging part at the measurement point is fatigued.

Abstract

Provided is a molding method for a composite material for molding a composite material by shaping a layered object including a plurality of layered fiber sheets using a mold and hardening the layered object. The composite material includes a bent part having a bent shape. The mold has a molding surface that molds the composite material, and a recess formed on a part other than the molding surface. The molding method comprises: a step for placing the layered object on the molding surface of the mold; a step for covering the layered object with a tension generation member that generates tension on the layered object during shaping, and placing a part of the tension generation member so as to face the recess; a step for covering, with a coating member, the layered object covered with the tension generation member, and sealing the part between the coating member and the mold in an airtight manner; a step for sucking the atmosphere between the coating member and the mold, drawing a part of the tension generation member into the recess, and shaping the layered object; and a step for molding the composite material by hardening the layered object after shaping.

Abstract

A method for molding a composite material that molds a composite material by shaping a laminate of a plurality of fiber sheets using a mold and curing, wherein the composite material includes a product part that serves as the part that will be molded as a product and a surplus part connected to the product part; the mold has a first molding surface that molds the product part, a second molding surface that molds the surplus part, and a depression for drawing in part of the laminate placed on the second molding surface; and the method comprises a step for placing the laminate in the mold with part of the laminate facing the depression, a step that covers the laminate by a covering member and creates an airtight seal between the covering member and the mold, a step that suctions the atmosphere between the covering member and the mold, draws part of the laminate into the depression, and shapes the laminate, and a step that molds a composite material containing the product part and the surplus part by curing the shaped laminate.
