摘要
借助有限元软件ABAQUS建立不同工况下的旋转双唇油封轴对称模型,基于单轴拉伸数据拟合Yeoh模型并进行油封的热-力耦合分析,得到油封的温度场和唇口的接触压力分布。利用红外热成像仪进行测温实验,通过对比油封唇口温升曲线仿真结果和实验结果,验证了模型的可靠性。此外,还研究了转速和弹簧力在干摩擦和良好润滑两种工况下对油封唇口温度场和最大接触压力的影响,结果表明,转速和弹簧力均会影响油封唇部温度分布,随着转速的增加油封唇口最高温度近似线性增大,而唇口最大接触压力没有变化;随着弹簧力的增加,油封唇口的最高温度和唇口最大接触压力均增大。
With the help of finite element software ABAQUS,axisymmetric models of rotary lip seal under different working conditions were established.Based on uniaxial tensile data,the Yeoh model was fitted and the thermal-mechanical coupling analysis was carried out to obtain the temperature field of the oil seal and the contact pressure distribution of the lip.The infrared thermal imager was used to measure temperature,and the reliability of the model was verified by comparing the simulation and experimental results of the lip temperature rise curve of the oil seal.In addition,the effects of rotational speed and spring force on the temperature field and maximum contact pressure of the lip of the oil seal under dry friction and good lubrication were also studied.The results show that both rotational speed and spring force can affect the temperature distribution of the lip of the oil seal.With the increase of rotational speed,the maximum temperature of the lip increases linearly,while the maximum contact pressure of the lip does not change;with the increase of spring force,the maximum lip temperature and the maximum contact pressure of oil seal are increased.
