Research On Conflict Resolution Method Of Low-carbon Design For Large Aerodynamic Equipment

The large aerodynamic equipment,a typical industry in Zhejiang province,has a wide range of applications and a sound economic performance,but there are many defects that restrict the products transforming to be green and low-carbon,such as complex structure,low reuse rate,high energy consumption,noise,etc.Accordingly,it is necessary and urgent to research on low-carbon design for large aerodynamic equipment systematically.The results not only make a breakthrough in sustainable design to promote the application of extensible design,but also provide a method to transform and upgrade the large aerodynamic equipment.A integrated method of extenics and TRIZ is illustrated by the case of screw air compressor,one of the large aerodynamic equipment,to research innovative coordination of complex technical conflict in low-carbon design.The works is described as below:1.For the problem on design purpose of low-carbon requirements of the large aerodynamic equipment,a generating method and a basic-element modeling method were put forward to aiming at the conflicts,which driven by low-carbon requirements,of prduct low-carbon design.The QFD mapping method was studied to clear the purpose.And with the lifecycle database of product low-carbon design,which was built by superposition principle,the extensible model of technical or non-technical conflict was built by the algorithm of multidimensional dependent functions.2.For the problem on modeling and classification of technical conflict of the large aerodynamic equipment,a classification modeling method,which integrated extenics and TRIZ,and a hierarchically conductive method were put forward to aiming at conflicts of prduct low-carbon design.The equivalent transformation mechanism and conflicts classification method were studied.Firstly,the interconversion and integration methods for technical conflict of extenics and TRIZ were put forward.And then the author studied the principle of mirror coordination of technical conflict problem based on AD theory.Finally,a dynamic transformation and conductive classification of technical conflict were constructed when requirements changed.3.For the problem on coordinating conflict of low-carbon performance of the large aerodynamic equipment,a top-down coordination method was proposed for low-carbon performance conflict.The simplified and reclassified models of conflicts problem of low-carbon design were built by clearing the correlation of low-carbon performance.And,a coordination strategy on core problem that causes low-carbon performance and a top-down coordination algorithm,with conductive and associated transformation,was proposed to generate innovative design of complex conflicts coordination.4.For the problem on structure variation and regeneration of low-carbon attribute conflict of the large aerodynamic equipment,a systematic coordination method,which intergrated extenics and TRIZ,was put forward to aiming at complex conflicts of low-carbon attributes.A mechanism of single or multiple structure transformation on coordinating core problem on low-carbon design was established with the 40 principles of TRIZ to calculate its realization probability by researching the principle of structure variation and regeneration of extensible core problem.With the guide of the TRIZ,three methods and its probability of structure variation and regeneration was shown in the paper.Finally,a software with the case of screw air compressor was programmed to test and verify the effectiveness and feasibility of the methods,for instance,the dynamic analysis of low-carbon requirements,the modeling of data and problem,the equivalent and dynamic transformation of technical conflict,the classification of technical conflict,the top-down coordination on performance conflicts,the coordination on complex attribute conflicts,and the probability of realizing innovative design.
