Abstract: According to the analysis of factors of damage (the self - excited vibration and the temperature field of violent fluctuation etc), the dynamics strength of hot roll is studied. Some thermal elastic-plastic non -linear dynamic models are established. The problem is calculated and analysed by using ADINA non-linear finite element program. The results are useful for design and manufacture of hot roll and operation of rolling process.
