Investigation on dynamic performances of a set of composite laminated plate system under the influences of boundary and coupling conditions

摘要: Abstract The method of reverberation-ray matrix (MRRM) is adopted to analyze the dynamic performance including free vibration and power-low transfer characteristics combination composite laminated plate system with arbitrary boundary coupling conditions. classical theory (CPT) a simple order shear deformation (S-FSDPT) are adopted. artificial virtual condition technology taken achieve At edges system, generalized forces displacements in local coordinates transformed into global coordinate each component according transformation relationship. By using technology, support springs at evenly arranged displacement direction under coordinates. changing spring stiffness value satisfy equilibrium relationship coordination conditions, thereby conditions coupled achieved. Through numerical calculation common “L” type, “T” type “□” structure, superior proved, it not limited by number plates angle. On this basis, effects material parameters on power flow its efficiency discussed separately.
