Study on the design of high pressure steel tube thickness control method based on TRIZ

为解决一种高压管壁厚控制问题,在基于传统控制方法的基础上提出解决管壁控制问题的模型和新思路。通过运用TRIZ创新理论,结合使用因果分析、冲突解决理论、物质-场分析及76个标准解等工具,构建了基于TRIZ理论的问题解决模型,寻找最优解决办法,来对管体壁厚进行准确测度,达到速度快、计算精确的技术特点和优势,并使用TOPSIS法进行方案择优选择。分析表明,最优方案能实现管体壁厚的高精度控制,实现壁厚控制合格率100%的目标。

To solve the problem of a high pressure tube wall thickness control, based on the traditional control method, this paper proposed the model and the new way of thinking to solve the problem of tube wall control. Using the theory of TRIZ, combined with causal analysis, the theory of conflict resolution, the material - field analysis and 76 standard solution tool, then construct the model of problem solving based on TRIZ theory, to find the accurate and optimal solution of the tube wall thickness, to achieve fast, precise calculation of technical characteristics and advantages, then preferential choice using TOP- SIS method. Analysis shows that the optimal scheme can achieve high precision control of ruble wall thickness, achieve the goal of wall thickness control and the percent of pass is 100%.
