烧结机台车的“塌腰”变形是目前生产中急待解决的问题。本文应用弹塑性断裂力学理论对其进行了分析研究,建立了台车热应变疲劳寿命的表达式,提出了提高台车应变疲劳寿命的若干措施。
Sintering machine trolley “collapse” distortion is the production of urgent problems. In this paper, the theory of elasto-plastic fracture mechanics is used to analyze the fatigue life of the trolley. The expression of fatigue life of the trolley is established and some measures to improve the strain fatigue life of the trolley are put forward.
