Abstract:

This work aims to present a general composite laminated plate-shell coupled structure (CL-PSCS) model for analyzing the transient vibration properties subjected to continuous moving concentrated/distributed excitations with high velocity. Thereinto, arbitrary constraint conditions at the coupling/boundary edges of the structural system are achieved by introducing the artificial virtual point coupling technology. By using the simple first-order shear deformation theory (S-FSDT), the in-plane rotational displacement/moment overflowing problem in the original FSDT is effectively avoided. Next, the limitation of the number of coupling substructures and coupling angle for the CL-PSCS is overcome by precisely dividing the moving excitation into several stages to imitate the uninterrupted loading mechanism. Then, the dynamic responses are obtained accurately by employing the multistage inhomogeneous term superposition and Fourier series expansion in the method of the reverberation-ray matrix (MRRM). The novelty of this paper is that the global-domain analysis for the CL-PSCS under continuous moving excitations is achieved for the first time. The accuracy and applicability of the present model and method are verified through the comparative evaluations of the common CL-PSCSs with ‘‘U'-shape type and ‘‘Ω'-shape type. Moreover, various parametric studies regarding the effects of structural and excitation parameters on the vibration reduction response are discussed. © 2023 Elsevier Ltd
