An effective engineering method was put forward to solve the dynamical problems of a ramjet combustion chamber liner made of C/C-SiC composite materials, in the absence of mechanical performance parameters of materials. The finite element model of liner was erected, and natural characteristics and vibration responses caused by random excitation were calculated. Then the design level was evaluated based on dynamical thesis. The study has a great reference value for vibration analysis on shell structure made of composite materials and dynamical design on shell structure used in ramjet.
