Abstract
A resin flow analysis method includes dividing a mold space model into small elements, acquiring a penetration coefficient, acquiring a flow conductance, and performing flow analysis of a resin in each of the small elements in the mold space model based on a first relational expression of the small elements of a base material portion relating to the penetration coefficient and a second relational expression of the small elements of a space portion relating to the flow conductance.
Claims8
A resin flow analysis method for performing flow analysis of a resin injected into a mold using a mold space model that includes a base material portion made of continuous fiber or a porous body arranged in a sheet form and a space portion in which the base material portion is not arranged, comprising:
- dividing the mold space model into small elements;
- acquiring a penetration coefficient that represents penetration characteristics of the resin into the base material portion;
- acquiring a flow conductance that represents flow characteristics of the resin in the space portion;
- and
- performing the flow analysis of the resin in each of the small elements in the mold space model based on a first relational expression of the small elements of the base material portion relating to the penetration coefficient, a viscosity of the resin, and a pressure and a second relational expression of the small elements of the space portion relating to the flow conductance, the viscosity of the resin, and the pressure.
A non-transitory computer-readable recording medium that records a program causing a computer to perform a resin flow analysis method for performing flow analysis of a resin injected into a mold using a mold space model that includes a base material portion made of continuous fiber or a porous body arranged in a sheet form and a space portion in which the base material portion is not arranged,
- the resin flow analysis method comprising:
- dividing the mold space model into small elements;
- acquiring a penetration coefficient that represents penetration characteristics of the resin into the base material portion;
- acquiring a flow conductance that represents flow characteristics of the resin in the space portion;
- and
- performing the flow analysis of the resin in each of the small elements in the mold space model based on a first relational expression of the small elements of the base material portion relating to the penetration coefficient, a viscosity of the resin, and a pressure and a second relational expression of the small elements of the space portion relating to the flow conductance, the viscosity of the resin, and the pressure.
