Knowledge Base for Innovative Design of Shearer based on Multi-level and Multi-granularity

The innovative design of shearer needs the support of a large amount of knowledge. According to the demand of innovative design knowledge in the innovative design process of shearer, based on the multi-granularity cognitive model, a multi-level and multi-granular shearer innovative design knowledge representation method and a instance-level knowledge description model are proposed and two different retrieval methods are designed. And then a knowledge base system for the innovative design of shearer is developed, which effectively assists designers to analyze and solve problems from different angles. Finally taking the improved design of roller structure of a certain type of shearer as an example, the support of knowledge base for shearer innovative design is validated.
