基于压力容器缺陷模糊评定的梯度分区

Gradient division based on fuzzy assessment of pressure vessel defect

为了对压力容器的缺陷进行模糊评定,需要为通用失效评定曲线组成的安全评定区域进行梯度分区。根据已有的模糊评定原理,以实现通用失效评定曲线的等距曲线为基础,对安全评定区进行了梯度分区,并在Visual Basic 6.0中通过程序实现,并达到了预期效果。

To fuzzy assess to defect （ s ） of pressure vessel, it is necessary that security area , that is structure by the currency failure assessment curve , is divided on gradient. Here utilizing a In-service principle of fuzzy assessment, producing curve offset of currency failure assessment curve, security area is divided on gradient , then approach which was produce on Visual Basic 6.0 also was put forward.
