The Effects of Centrifugal Stress on Seal Dynamics

시일 동특성에 미치는 원심응력의 영향에 관한 연구

The dynamic characteristics of the annular pressure seal employed in pump have been theoretically deduced with consideration of the effects of elastic deformation due to the centrifugal stress. The deformation of the shaft is governed by the linear theory of elasticity. The results derived herein considering the elastic deformation are compared with the previously published author's results in the stiffness and damping coefficients.
