| 目的 利用发明问题解决理论(TRIZ)设计一种试验平台，来解决模切机上的模切压力难以直接检测的问题。方法 首先文中引入光纤Bragg光栅传感器来检测模切压力，针对光纤Bragg光栅传感器自身特点，结合TRIZ理论中的因果链分析与完备性法则，形成直接检测模切压力的初步设计方案。其次利用矛盾解决原理提高初步设计方案中的稳定性、测量精度和抗变形性，并通过物质–场模型分析法对初步设计方案中的底座结构进一步优化，得到试验平台的总体设计方案。最后对试验平台的关键零件进行静力学分析和模态分析。结果 关键零件——顶板的最大应力和最大变形量分别为77.063 MPa、0.525 24 mm，表明强度和刚度均满足要求，并且不会发生共振现象，验证了基于TRIZ理论设计的试验平台可以满足光纤Bragg光栅传感器的工作要求。结论 利用TRIZ理论来指导模切压力试验平台的创新设计，为精确测量模切机的模切压力提供了新方法。 |

| The work aims to design a test platform based on TRIZ theory to solve the problem that it is hard to directly detect the die-cutting pressure on the die-cutting machine. Firstly, the fiber Bragg grating sensor was introduced to detect the die-cutting pressure. According to the characteristics of the fiber Bragg grating sensor, and combined with the Cause Effect Chain Analysis and completeness rule in TRIZ theory, a preliminary design scheme for directly detecting the die-cutting pressure was formed. Secondly, the stability, measurement accuracy and deformation resistance in the preliminary design scheme were improved with the principle of conflict resolution. The base structure in the preliminary scheme was further optimized by the material-field model analysis method. And the overall design scheme of the test platform was obtained. Finally, the static analysis and modal analysis of the key part of the test platform were carried out. The maximum stress and maximum deformation of key part, the top plate, were 77.063 MPa and 0.525 24 mm respectively, indicating that both strength and stiffness met the requirements, and resonance would not occur. It was verified that the test platform designed based on TRIZ theory could meet the working requirements of fiber Bragg grating sensor. The innovative design of the die-cutting pressure test platform guided by TRIZ theory provides a new method for accurately measuring the die-cutting pressure of die-cutting machine. |
