doi:10.11930/j.issn.10.11930.2015.1.56

Abstract

Abstract: To evaluate the quality of nuclear level Ⅰ forgings comprehensively and objectively, it is necessary to establish a set of method systems which are suitable for forging quality evaluation. According to the manufacturing process and final quality inspection which affect the quality of nuclear level Ⅰ forgings, the main process parameters are analyzed and the forging quality evaluation index system is established. By exploring the characteristics of TOPSIS method based on entropy weight, the evaluation model is established and applied to the core barrel forging material quality evaluation, and the core barrel forging material quality order is obtained. The results show that the TOPSIS method can evaluate the quality of nuclear level Ⅰ forgings effectively, scientifically and objectively; it is convenient to operate and easy to apply.

Key words: nuclear power plant, nuclear level Ⅰ forging, entropy weight, TOPSIS, quality evaluation
