| Abstract: | The elastic cushion layer between the steel spiral case and surrounding concrete is often used as a structural type in the large-scale hydropower plant in China.In view of the uncertainty of the optimal elastic coefficient of friction and the transfer mechanism of internal water pressure to the surrounding concrete,the spiral case with cushion layer of a large-scale hydropower plant is simulated with ANSYS nonlinear finite element program.Then considering the slip contact characteristics between the steel s... |
