Mode shape functions of free paraboloidal thin shells

  • Based on the membrane theory, a set of mode shape functions for paraboloidal thin shell with free boundary condition were formulated. Low mode shapes of free paraboloidal thin shell were obtained by the way of modal experiment analysis. The theoretical mode shapes based on the mode shape functions were compared with the mode shapes through finite element method and experimental method. The results show that the theoretical mode shapes agree well with the mode shapes through finite element method and experimental method. Then mode shapes of paraboloidal thin shell can be correctly described by the mode shape functions.
