A method and system for intelligent matching of material selection for die steel

Abstract

The application discloses a material selection intelligent matching method and system for die steel, and relates to the technical field of die material selection. The method comprises the following steps: obtaining working condition parameter information of a target die steel, and constructing working condition characteristic vectors of each working condition stage; constructing a performance requirement vector based on the working condition characteristic vectors; extracting index vectors of each requirement index based on the performance requirement vector, and constructing a performance relationship matrix; obtaining performance quantization value vectors of each working condition stage of each candidate die steel in a material database, calculating stage performance adaptation degrees, and forming a material adaptation degree sequence of each candidate die steel; and further calculating a stable matching index of the candidate die steel under all working condition stages, so as to obtain a material selection result. The technical problem that it is difficult to accurately match multiple working conditions, multiple indexes and coupling relationships among indexes in the existing die steel material selection process is solved.
