| Abstract: | By using the finite difference method,the press field of a new structure floatation cushion was simulated.Gas film pressure distribution and carrying capacity of the floatation cushion are studied through theoretical analysis.By utilizing overlapping stitching technique,the carrying capacity and stiffness were obtained by using the coupling procedure of the gas lubrication governing equation and elastic deformation of membrane governing equation.The results of theoretical calculations show that the effect o... |
