摘　　要：针对机械密封在高参数复杂工况下易磨损、易泄露等缺点,选取内圆弧槽机械密封动静环为研究对象,利用耦合梯度迭代的方法对密封副的压力场和热力场分别进行仿真计算。结果表明:转速越高,机械密封端面流场的动压效应越明显;内圆弧槽区流入流体的一端的温度明显低于槽区排出流体的一端,而且流入流体一端是整个槽区温度最低的集中区域;圆弧槽密封副动环端面热应变和热应力变化明显,而且接触面是整个密封副耦合效应最明显的区域。研究结果为以后研制新型槽型奠定基础。A iming at the defects of the mechanical seal under high parameters, such as easy to wear, easy to leak, and so on, selects the inner circular groove mechanical seal ring as the research object, using the method of coupled gradient iteration method to simulate the pressure field and the thermal field of the seal pair. The results show that the pressure of the pressure drop and the dynamic pressure of the circular groove is lower than that of other regions, and the temperature decreases gradually from one side to the other. The thermal stress and the thermal strain decrease with the increase of the distance.
