Abstract
Abstract. The structure of the lightweight honeycomb sandwich panel
is complex. Thus, establishing an equivalent simplified model is
indispensable to improve the efficiency of the dynamic analysis of honeycomb
sandwich panels. In this paper, three commonly used dynamically equivalent
modeling methods for honeycomb sandwich panel are studied: a dynamically
equivalent method based on laminated plate theory, a single-layer plate
equivalent method based on the theory of Hoff (1948), and an improved equivalent
method based on Allen (1969). Using theoretical study, numerical simulations, and experiments, the
applicability of these equivalent methods and the effect of design
parameters on the dynamic characteristics are studied, and the optimal
dynamically equivalent method for honeycomb sandwich panels is obtained.
