摘　　要：文中建立燃气轮机仿真模型和后传动设备动力学仿真模型代替传统数学模型方法,采用联合仿真方法得到快速并车工况下关键部件的冲击载荷、接触力的变化规律.在此基础上,采用有限元方法对系统关键部件在最大碰撞力下的接触特性进行瞬态动力学求解,得到关键部件在最大碰撞力下应力变化情况以及危险位置.The gas turbine simulation model and the dynamic simulation model of rear transmission equipment were established to replace the traditional mathematical model method,and the change law of impact load and contact force of key components under the condition of fast parallel operation was obtained by joint simulation method.On this basis,the contact characteristics of key components of the system under the maximum impact force were solved by finite element method,and the stress changes and dangerous positions of key components under the maximum impact force were obtained.
