中文摘要:
      考虑摩擦生热、热滞后热源对旋转轴唇形密封圈温度场的影响,模拟油封在特定工作条件下的温度分布。应用有限元分析软件ABAQUS,建立唇形油封的三维有限元模型,并对某优化前后的唇形油封的非稳态温度场进行仿真,获得压力、转速与油封温升之间的关系曲线。仿真结果表明:该优化前后的唇形油封的温度场分布均满足密封要求;且在分析的工作参数范围内,密封圈温度随压力的增大而减小,随转速的增加而增大;摩擦面上的温度从两侧向中间逐渐增加,最高温度位于中间位置靠近空气侧;且优化后的油封随着转速的增大和压力的升高,温度的变化幅度趋于平缓,证实了优化后油封的较好密封性能和散热性能。
英文摘要:
      Considering the influence of the heat generation mechanisms by friction and hyperelasticity theory on the temperature field of the rotating shaft lip seal, the temperature distribution of the oil seal under specific working conditions was simulated.The three dimensional finite element model of lip seal was established by using the finite element analysis software ABAQUS.The unsteady temperature field of a lip seal before and after optimization was simulated and the relationship curves between pressure,speed and oil temperature were obtained.The simulation results show that the temperature field distribution of the rotary shaft lip seal before and after optimization satisfies the sealing requirement. In the range of the analyzed parameters,the temperature of the seal ring is decreased with the increasing of the pressure,and increased with the increasing of the rotational speed.The temperature on the friction surface is increased gradually from the two sides to the middle, and the maximum temperature appears at the center close to the air side.The change of temperature of the optimized oil seal tends to be smooth with the increasing of the rotational speed and the pressure,which proves that the optimized oil seal has better sealing performance and heat dissipation performance.
