TRIZ 理论在掘进机截割头设计中的应用
Application of TRIZ theory in the design of roadheader cutting-head
摘要
Abstract
In order to improve the cutting performance of the roadheader further and reduce the wear of picks ,the Theory of the Solution of Inventive Problem (TRIZ) was studied .By using the conflict concept ,the conflict resolution principles and problem solving method in TRIZ ,ques‐tions were analyzed ,mainly focused on how to optimize the arrangement of picks of cutting‐head , how to improve the efficiency of cutting ,how to improve the force of picks and how to reduce the wear of picks .And under the inspiration of the 15th inventive principle (dynamic character princi‐ple) ,the specific solution which was using the arrangement of variable angel spiral of picks was obtained .According to this idea and combined with regular design method of cutting‐head ,three cutting‐heads whose picks were arranged in different kinds of variable angel spiral were devel‐oped .The energy consumption of cutting‐ratio along with the original cutting‐head were tested and the experiment showed that the cutting‐head of J23 type performs efficiently and stably .It could be finalized and produced after some little improvement .关键词
