Comparative Analysis and Selection of Seal Structure between the Piston and Casing of Rapping Device
ANSYS was employed to build nonlinear finite element models of seal structure of double-Y and quad-ring between the piston and casing of rapping device respectively. The relationships of the contact stress versus fluid pressure and the Von-Mises equivalent stress versus working pressure of fluid were obtained. The comparison of the two calculated results presented the seal structure of double-Y was proper for rapping device between the piston and casing.
