Why is the A4 value still zero after strengthening the solid-forged part using SW6-2011?
Thread Content
Was it my wrong parameter input that caused the reinforcement of the SW6 solid forged part? It’s still the software that’s broken; since it doesn’t meet the requirements, reinforcement rings cannot be used for reinforcement
Overall reinforcement, with the reinforcement area indicated by A1/A2; A1 represents the excess material of the equipment itself, while A2 denotes the reinforcement area of the connecting pipe. You already said there’s no need for a reinforcement ring, so of course A4 is zero
A4 refers to the reinforcement area of the reinforcement ring; it is naturally 0 in the absence of a reinforcement ring.
