Abstract Based on the theoretical approach of multi-body interaction dynamics, a theoretical model is constructed to simulate the nonlinear response amplification of the projectile structure. The accuracy and universality of the theoretical model wer

The reentry vehicle is in an unconstrained free-flight state during the reentry process. The pressure of air fluctuations acts on the external surface of the vehicle and induces a random vibration environment with a wide-frequency range, which makes

This study investigates the nonlinear free vibration of functionally graded material (FGM) beams by different shear deformation theories. The volume fractions of the material constituents and effective material properties are assumed to be changing i

The nonlinear dynamic modeling by combining the equivalent linear mechanics with the multi-objective optimization algorithm is proposed to describe the nonlinear behaviors of the joint interfaces. The joint interfaces are simplified as the equivalent

An elastic and plastic mechanical model is proposed to characterize the normal contact of rough surfaces. The contact process is considered as three separated contact regimes, i.e., the fully elastic, mixed elastic–plastic and fully plastic ones. T

The complex frictional stick-slip behaviors of mechanical joint interface have a great effect on the dynamic properties of assembled structures. In this paper, a reduced-order modeling approach based on the constitutive Iwan model is proposed to desc

The mirror array system is widely used in the large-scale inertial confinement fusion (ICF) facility. The rotation responses of array mirrors have a great influence on the beam drift stability of the ICF facility, while the stiffness of each componen

A fast computation scheme and its corresponding reconstruction model for the gravity anomalies along glide trajectories of a hypersonic vehicle are initially proposed. Further, the optimization algorithm for the reconstruction model is developed base
