Triz理论在滚动轴承故障诊断中的应用

Application of Triz Theory in Fault Diagnosis of Rolling Bearing

运用Triz创新理论致力于解决滚动轴承故障诊断准确率不高问题,根据创新方法的系统功能分析、系统因果分析和系统资源分析三大分析方法,列举负面功能,寻找根本原因,识别可用资源,确定问题突破点。首先,应用Triz理论的系统裁剪、物-场模型及标准解、技术矛盾和物理矛盾工具为解决滚动轴承故障诊断问题提供8个创新方法。随后,使用九屏幕法确定资源方案和使用尺度-时间-成本算子讨论极限条件下的解决方法。接着,分析达到理想化最终解的障碍是设备智能化程度低,数据采集和处理能力不足,缺少先进的故障预测和诊断技术,同时探讨不出现这种原因的条件。最后利用评价方法对方案的经济性、可行性和可靠性综合评价,提出了一种解决滚动轴承故障诊断问题的方法,具有重要的实际应用价值。

The Triz innovation theory is opplied to solve the problem of low accuracy of rolling bearing fault diagnosis.According to the system function analysis,causal system analysis,and system resource analysis of the innovation method,the adverse functions are listed,the root cause are found,the available resources are identified,and the breakthrough point of the problem is determined.First,eight innovative methods are provided to solve the problem of rolling bearing fault diagnosis by applying the system tailoring of Triz theory,matter-field model and standard solution,technical contradiction,and physical contradiction tools.Then,the nine-screen method determines the resource plan,and the scale-time-cost operator is used to discuss the solution under limited conditions.Then,it is analyzed that the obstacles to achieving the ideal final solution are the low level of equipment intelligence,insufficient data acquisition and processing capacity,and lack of advanced fault prediction and diagnosis technology.At the same time,the conditions for elimunating this cause are discussed.Finally,a method to solve the problem of rolling bearing fault diagnosis is proposed by using the evaluation method to comprehensively evaluate the scheme\s economy,feasibility,and reliability,which has significant practical application value.
