| Abstract:This study introduced the evolutionary relationship between the tissue pattern and the wear time of blade. Based on the observation and analysis of the adhesive layer of the Yangkee dryer during the use cycle of the blade， the evolution of the adhesive layer was actually the elastic modulus evolution of its material under different deformation rates. Through introducing the concept of the deformation area of the adhesive layer caused by pressure and simplifying the physical model using three assumptions， a mechanical analysis was conducted on the small stress zones before and after the impact point. The mathematical relationship model between the average geometric length of the paper patterns and the wear time of the blade was theoretically derived， and the model was simplified under the condition of stable operation of the paper machine for ease of verification. Through practical production verification of the paper machine， the mathematical model was reliable and practical. |
