螺旋波纹钢管机的创新设计
Innovative Design of Spiral Corrugated Steel Machine via TRIZ-QFD

针对现有螺旋波纹钢管机存在的问题,利用QFD法确定出各个需求和工程特性之间的权重关系并确定出需求的改进率;运用TRIZ理论提取设备中存在的物理冲突和技术冲突,并对照39个参数和40个发明原理确定出解决冲突的可行方法;结合波纹钢管机本身的功能需求及结构特点对其结构进行了创新设计。经有限元分析中的模态分析验证本创新设计是合理的。
Aiming at solving the existing problems and shortcomings of current spiral corrugated steel machine, firstly, the weight factors between the requirements and engineering characteristics and the rate of improvement were determined with the QFD. Next method, the physical and technical conflicts were extracted according to the TRIZ method. Then the parameters, which were necessary to modify, were found out by comparing 39 parameters. Meanwhile, 40 invention principles were used to determine the feasible way to solve the problem. Thirdly, a new type of spiral corrugated steel machine was designed based on the functional requirements and structural features of corrugated steel machine. Finally, the innovation design was reasonable according to the analysis results via finite element method
