摘要
利用大型有限元软件ANSYS对齿条板的温度场和应力-应变场进行分析,研究在空气冷却过程中的温度和应力分布、时间历程及收缩变形与完工公差的比较。建立可行的齿条板冷却过程中温度场、应力场的动态模拟方法,为JU2000E平台的齿条切割提供参考。
The temperature field and stress strain field changes of the rack plate with the finite element analysis software ANSYS are analyzed,including the distribution time history of temperature and stress and the comparison of shrinkage deformation and completion tolerance.A feasible dynamic simulation method on temperature f ie ld , stress and deformation of rack cooling process is established. I t provides theory foundation and instruction for the flame cut-ting of JU2000E rack plate.
