| Abstract: | The temperature and stress fields of the rotary steam-distributing valve system in thermal power underwater vehicle are simulated by using three-dimensional finite element method. Contact stress between the valve body and valve base of this system is analyzed. According to the simulation results, a method to improve the valve body strength is presented to optimize the design of the valve system. |
