摘　　要：利用预应力法研究了转子系统在启动时的动态特性,计算了转子系统在加速过程中的应力和振动特性。在此基础上,分析了转子过临界转速时的扭转变形和弯曲变形。The prestress method is used to study the dynamic behavior of a starting rotor. It is calculated the stress and vi- bration of the rotor. It is analysed the lateral and torsional deformation as the rotor speed to pass the critical speeds.
