摘要：

This paper puts forward dry gas seals with novel face grooves that are called as hyperelliptic curve grooves. At high PV value, gas film dynamic characteristic coefficients isoline distributions are obtained under the different polar angle and hyperelliptic coefficient. Disturbance behaviors of gas film thickness and pressure are studied whether there is angular excitation or not. Saltation peak and period peak are defined, and their isoline distributions are presented which reveal the influence mechanism of gas film dynamic characteristics coefficients on dynamic tracking property. A dynamic wedge-shaped gap with a fixed angle between seal faces will form under the influence of angular excitation, and it has a significant impact on transient behaviors of the dry gas seals.
