“…Besides, when keeping either the number of tightening bolt or tightening torque as a constant, both the simulation and test results imply that the natural frequencies of the bolt connection structure have the proportional relationship with the other parameter, which is in good agreement with the results in Tang et al 9 and Wei et al 12 1. Based on the theoretical analysis of contact stiffness and structural rigidity of bolt connection structure, the structural natural frequencies will change with the increase in pretightening force and the number of tightening bolts.…”

“…There are only a few studies on vibration characteristics of a bolted disk-drum joints structure (where the disk and drum are joined by a number of bolts), because of the particularity of this structure. Tang et al 9 investigated the modeling and dynamic analysis method of a bolted joined cylindrical shell. Different kinds of factors, including the number of bolts, load frequency, excitation amplitude, and preload, were considered to influence the dynamic behaviors of the cylindrical shell.…”

In a bolted disk-drum joints structure, assembly parameters, such as the number and pretightening force of the tightening bolts, will affect the vibration characteristics of the structure. In this article, the influences are discussed. First, the influences of contact and structural stiffness on the natural characteristics of the joint structure are analyzed theoretically. Considering the micro-contact between the contacting surfaces of the bolts' connected structure, the stress diffusion between the bolt head and the disk is investigated. Then, the relationship between the tightening torque and contact stiffness, as well as the relationship between the number of tightening bolts and structural stiffness, is established. Furthermore, the relationship between assembly parameters and the natural frequencies is obtained. Hence, the regularity of the influence on the structural natural frequencies can be summarized as a consequence. The results of experiment showed that the minimum error between theoretical calculation and experimental data was 1.5%, which provides a reliable analysis tool for the investigation of vibration characteristics on the bolted disk-drum joints structure.

“…Li et al [19,20] studied the geometrically nonlinear vibration of noncontinuous elastic-supported laminated composite cylindrical thin shells by extending a new arcssupported and points-supported shell model. Tang et al [23,24] considered the three contact states of bolted connection, including stick, slip and separation, and established a piecewise linear boundary analytical model of bolted cylindrical shells, and studied its dynamic characteristics. Li et al [25] presented a model of laminated composited cylindrical shells with arc supported and point supported elastic boundary condition based on Donnell's shell theory, the Chebyshev polynomials and the Lagrange equation.…”

In this paper, the nonlinear vibration control of the piezoelectric laminated cylindrical shell with point supported elastic boundary condition is analyzed, in which the geometric nonlinearity is considered by the first-order shear nonlinear shell theory. In the model, different boundary conditions are simulated by introducing a series of artificial springs. The elastic-electrically coupled differential equations of piezoelectric laminated cylindrical shells are obtained based on the Chebyshev polynomials and Lagrange equation, and decoupled by using the negative velocity feedback adjustment. Later, the Incremental Harmonic Balance Method (IHBM) is deduced, and the frequencyamplitude response of the piezoelectric laminated cylindrical shell is obtained by IHBM. Finally, the influence of the constant gain, size and position of the piezoelectric layer on frequency-amplitude response are investigated. The results show that the position, size and constant gain of the piezoelectric layer have a significant influence on its nonlinear vibration control.

“…The characteristic orthogonal polynomials, obtained by the Gram-Schmidt orthogonalization process, can satisfy various geometric boundary conditions. 22,[43][44][45][46] Owing to the perfect property of the polynomials, the more natural characteristics can be accurately predicted by the proposed model. Furthermore, to improve calculation efficiency and obtain satisfactory results, the number of orthogonal polynomials used in the numerical simulations can be determined according to the need of calculation precision.…”

This paper focuses on the free vibration analyses of the rotating hard-coating cylindrical shells with various boundary conditions and the effects of hard coating on the vibration behaviors of the rotating shells. To accurately predict more natural characteristics, the characteristic orthogonal polynomials are taken as the admissible displacement functions. Considering the influences of Coriolis force, centrifugal force and initial hoop tension caused by rotation, the equations of motion of the shells are established by the use of the Rayleigh-Ritz method. Based on the state vector method, an efficient method is developed to solve the equations. By comparing with the results of both the finite element analysis and published literatures, the high accuracy and good convergence of the proposed model are verified. In addition, the effects of the boundary conditions, parameters of hard coating, rotating speed and number of circumferential waves on the vibration behaviors of the hard-coating shells are evaluated. This study may provide a reference for the application of hard-coating damping treatment to the vibration suppression of rotating thin-walled structures.
