The ARIZ algorithm within TRIZ was mainly applied to solve complex problems. ARIZ integrated many tools of TRIZ and presented the entire flow process from problems analysis to evaluation of scheme solution. Energy-saving design of cutting drum on shearer was one of the main research directions of drum shearer designers. Drum shearer's operated principle was introduced as well as cutting coal and coal-loading process and the problem of larger cutting drum energy-exhausting. It was known that the reason of larger cutting drum energy-exhausting was forming cutting volume of crescent moon type by analysis of Pro/InnovatorTM 5.0 software about energy-exhausting problem i.e. coal was excessively broken at the tip of crescent moon, at the same time, friction was formed easily because the directions were different between drum revolution and feed direction. With other energy-exhausting, they occupied a large proportion of cutting power. Only analogy scheme was inquired in knowledge base of innovation method. The nine key procedures were put into effect step by step according to ARIZ flow process. Finally, the effective energy-saving scheme was formed through derivation resources development i.e. adopting the middle part of vertical cutting drum, cutting coal along with parallel direction of bedding and setting high regulating hydraulic cylinder into drum internal part. The ARIZ algorithm' validity is verified through energy-saving scheme design process of shearer on solving complicated engineering problem.%TRIZ理论中的ARIZ算法主要用于解决复杂问题,ARIZ集成了TRIZ的多个工具,给出了从问题分析到方案解评价的整个流程.采煤机截割滚筒的节能方案设计是滚筒采煤机设计者的主要研究方向之一.介绍了滚筒采煤机工作原理和截煤、装煤过程,指出截割滚筒工作过程中存在能耗大的问题.通过Pro/InnovatorTM5.0软件对能耗问题分析发现,采煤机截割滚筒能耗大的原因是在截煤时形成月牙形截割体,在月牙尖处截齿对煤的截割过度破碎,同时底部的月牙尖处由于滚筒的转动方向与进给方向不一致,容易引起煤壁与截齿的接触摩擦,连同其他部分的能量损失,占有截割功率很大的比例.查询技术创新知识库结果只有类比方案.按照ARIZ流程,逐步实施9个关键步骤,最终通过派生资源的发掘形成了有效的节能方案,即采用中间剖分的立式截割滚筒、平行于层理方向截割煤层及将调高油缸设置在截割滚筒内部.采煤机截割滚筒节能方案设计过程证明了ARIZ在解决复杂工程问题的有效性.
