| 摘 要： | In this paper the static stress distribution of closed valve during diastole under the peak across valve pressure difference is analyzed with nonlinear finite element method. We analyzed the three shapes i. e.,spherical,cylindrical and rotating paraboloid type valves, respectively as a result of computation, it is suggested that the maximum principal normal and shearing stress for rotating paraboloid type valve are smaller than those for the cylindrical and spherical type valves. It shows that there exist some similarities of the stress distribution among these three type valves.
