Abstract: In this paper, the natural characteristics of fiber-reinforced thin-walled conical-cylindrical composite shells with bolted
connection are analyzed through theoretical calculations and experiments. The cylindrical shell and the conical shell are modeled
separately based on the classical theory of layer rationality and the Kirchhoff-Love hypothesis. According to the connection charac⁃
teristics of fiber-reinforced thin-walled conical-cylindrical composite shells, the artificial spring method is introduced to realize arbi⁃
trary bolt connection conditions at the joint of the composite shell. The influences of both the primary and secondary springs were
respectively considered. The Rayleigh-Ritz method and two-term beam function method are used to solve the natural characteristics
of fiber-reinforced thin-walled conical-cylindrical composite shells. The TC300/epoxy fiber-reinforced thin-walled conical-cylindri⁃
cal composite shells are used as the research object, and the single-point hammer response test is carried out. Finally, the experi⁃
mental results show that the error between the calculated natural frequency and the test results is in the range of 2.7%~4.5%,
which verifies the rationality of the model established in this paper. The influence of bolt missing at the joint on the natural charac⁃
teristics of fiber-reinforced thin-walled conical-cylindrical composite shells is discussed based on the above model, by changing the
bolt stiffness at the joint and simulating the missing of bolts.
