基于TRIZ理论的磁悬浮桥梁支座创新设计

Innovative design of maglev bridge bearing based on the TRIZ theory

以磁悬浮桥梁支座为研究对象,对其进行功能分析和问题分析。利用TRIZ理论提取系统中存在的技术矛盾,对照39个工程参数和40个发明原理建立矛盾矩阵,并利用发明原理对支座中的部分结构及总体结构进行创新设计。根据TRIZ理论提出的磁悬浮桥梁支座创新设计方案,进行样品试制及系列试验;试验结果表明,支座各项力学性能及功能均满足设计和标准要求,支座具有传力可靠、结构紧凑、高度无级可调、横向位置无级可调等优点,可以为相关磁悬浮桥梁工程建设提供参考。

Taking the maglev bridge bearing as research object,the function analysis and problem analysis of the maglev bridge bearing were carried out.The technical contradictions in the existing maglev system were extracted by using TRIZ theory,and a contradiction matrix was established by comparing 39 engineering parameters and 40 inventive principles.Innovative design of partial structure and overall structure of the maglev bridge bearing was carried out by using inventive principles.According to the innovative design scheme of maglev bridge bearing proposed by TRIZ theory,sample trial production and series of tests were carried out.The test results show that the mechanical properties and functions of the bearing meet the design and standard requirements.The bearing has the advantages of reliable force transmission,compact structure,stepless adjustable height and stepless adjustable transverse position,which can provide reference for related maglev bridge construction.
