基于临界平面法的直振筛板疲劳寿命分析
Fatigue life analysis of linear vibrating screen plate based on critical plane method
摘要
Abstract
Aiming at the multi-axial fatigue failure problem caused by the long-term cyclic load of the linear vibrating screen plate in the cigarette production line,research on its fatigue life prediction and life distribution is carried out.Taking the rework cigarette production line equipment of a certain factory as the research object,its dynamic model is constructed according to the actual operating conditions,the force of the elastic element is solved,and the force is imported into ANSYS as the input condition for finite element analysis,so as to obtain the stress distribution during the operation of the vibrating screen.By extracting the results of stress components and combining them with the multi-axial high-cycle fatigue life prediction model based on critical plane method,the fatigue life of linear vibrating screen plate is evaluated,and the fatigue risk parts of the structure are identified.With the aid of dynamic modeling,static analysis and multi-axial fatigue theory,a comprehensive analysis method suitable for cigarette equipment under constant amplitude loads is proposed.The research results show that the damage degree of the vibrating screen surface is relatively small.The maximum force-bearing part is located at the connection between the lower screen surface and the shock-absorbing spring,which has a high consistency with the position of the lowest service life point.关键词
