چکیده
A precise transfer matrix was employed to analyze the free vibration characteristics of a cord-reinforced air spring with winding formation under preload conditions. The abstracted as rotary combined shell structure variable trajectory characteristics. structure, which consisted cylindrical and toroidal shells, analyzed for its pre-stress theory thin shells create control equations effect. Helmholtz equation used influence sound pressure inside fluid–structure coupling boundary derived from equation, geometrical physical shells. Under continuous conditions state vector between were into obtain total equation. considered solve natural frequency spring. calculation results compared prototype test simulation verify effectiveness accuracy theoretical model. On this basis, we explored axial half wave number, circumferential material on research findings would provide important significant guidance structural design springs formation.

Free vibration of rectangular plates with continuously distributed spring-mass
The vibratory characteristics of rectangular plates attached with continuously and uniformly distributed spring-mass in a rectangular region are studied which may represent free vibration of a human–structure system. Firstly, the governing differential equations of a plate with uniformly distributed spring-mass are developed. When the spring-mass fully occupies the plate, the natural frequencie...
متن کاملVariational Iteration Method for Free Vibration Analysis of a Timoshenko Beam under Various Boundary Conditions
In this paper, a relatively new method, namely variational iteration method (VIM), is developed for free vibration analysis of a Timoshenko beam with different boundary conditions. In the VIM, an appropriate Lagrange multiplier is first chosen according to order of the governing differential equation of the boundary value problem, and then an iteration process is used till the desired accuracy ...
متن کاملFree Vibration of Lattice Cylindrical Composite Shell Reinforced with Carbon Nano-tubes
The free vibration of the lattice cylindrical composite shell reinforced with Carbon Nano-tubes (CNTs) was studied in this study. The theoretical formulations are based on the First-order Shear Deformation Theory (FSDT) and then by enforcing the Galerkin method, natural frequencies are obtained. In order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...
