Conceptual Design Of Electro-haulage Shearer Based On TRIZ Theory

The objective of electro-haulage shearer's conceptual design is to put forward programs of electro-haulage shearer's innovation design and improve its idealizing level.The thesis firstly introduced the meaning, characteristics and effect of conceptual design as well as general situation of TRIZ, its application and main contents, then produced frame and flow diagram of innovation design basing on mechanical products' conceptual design and TRIZ theory. At same time, the flow of diagram was applied to innovative design of electro-haulage shearer and formed innovating conceptual program.The method is means of forming innovating conceptual design program on innovation-type mechanical product and in favor to improve the idealizing level of mechanical product.In allusion to actuality of development and manufacture on electro-haulage shearer at present, the thesis carried on several tasks as follow:1. The conceptual design frame and flow of innovation are brought forward basing on flow of mechanical products' conceptual design and innovating flow of TRIZ theory.2. Built up function structure model of electro-haulage shearer. The state of insulation was conquered between cutting movement and haulage movement, and their affiliation was built up at the base of cutting coal's analysis on excavator. It could realize the requirement function location of engineering problem. This established the basis for finding out technique system assemblies of engineering problem on mechanical products.3. Realize the function location of engineering problem in allusion to client requirements and function structure of electro-haulage. The function-connection analysis and root case analysis that based on TRIZ theory were finished about assemblies of electro-haulage shearer and the preparations in advance were ready for resolving engineering problem with TRIZ theory.4. Defined the technical contradictory and physical contradictory by root case analysis and put forward conceptual design program of electro-haulage shearer by applying to innovation principle and substance-field analysis grounding on Law of Idealizing Degree of TRIZ. The innovating program senior to original program was known by results of two-stage fuzzy synthetical evaluation.
