    摘要:

    建立W形金属密封环的有限元模型,计算其不同工况下的静力学状态,并以此为基础探究W形环最大Von Mises应力与最大接触应力的影响因素。运用ANSYS模拟W形环在不同工况下加载卸载的全过程,探究W形环回弹率的各种影响因素。结果表明:在计算范围内,壁厚和压缩量的增加使最大接触应力平稳增大,密封性能提高,波高和温度的增加使最大接触应力下降,密封性能下降;壁厚和压缩量的增加使回弹率降低,波高与介质压力的增加使回弹率升高。

    Abstract:

    W-sealing ring is a kind of elastic metallic seal which is used to solve sealing problem in extremely working conditions in aerospace field.A finite element model of Wring was built and its working stress under different states was analyzed.The influencing factors of maximum Von Mises stress and maximum contact stress were explored.The whole loading and unloading process of W-ring under different working states was simulated by using ANSYS and the influencing factors of compression recovery rate were explored.It is found that in the calculation range,the increase in wave thickness and compression displacement causes the increase of maximum contact stress and the improvement of sealing property,and the increase in wave height and temperature causes the decrease of maximum contact stress and sealing property;the increase in wave thickness and compression displacement causes the decrease of compression recovery rate,and the increase in wave height and pressure causes the increase of compression recovery rate.
