本文介绍用动静法将动态过程处理为静态,将密封副摩擦面处理为只能承受压力的特殊杆单元,由此建立起机械密封的有限元模型,并对7种不同结构的密封环进行了力学计算,其计算结果与实验结果较接近。
In this paper, the static and dynamic method is used to process the dynamic process into a static state. The friction surface of the seal pair is treated as a special rod unit that can only withstand pressure. The finite element model of the mechanical seal is established. Seven kinds of seal rings with different structures are introduced Mechanical calculation, the calculation results and experimental results are closer.
