A dynamic modelling approach for a multi-beam structure connected with nonlinear joints is
presented and subsequently used to obtain its reduced-order analytical model. Firstly, by …

This paper investigates the dynamic characteristics and vibration transmission behaviour of
interactive oscillators with nonlinearities at their coupling interface. Three different types of …

Deployable trusses that are widely applied in space missions utilize many hinged members
to adapt to different geometrical shapes and work conditions. This paper presents two …

Joints in deployable structures can degrade the stiffness and the stability of spacecraft. In
this study, the nonlinear stiffness of spherical joints is investigated. The traditional contact …

A large number of joints that make possible the smooth deployment of an articulated truss
may lead to the unexpected variation of the whole dynamic characteristics of the truss. In this …

A frequency domain based algorithm using Fourier approximation and Galerkin error
minimization has been used to obtain the periodic orbits of large order nonlinear dynamic …

In this study, a method is developed for parametric identification of nonlinear element in
structure. A concept of sub-structure synthesis is used to derive the frequency equation in …

Clearance joints significantly affect the dynamic properties of deployable structures (DSs).
This paper presents a spring-mass model with clearance for the study of the axial stiffness of …

Solutions for analytical models of systems with nonlinear constraints have focused on exact
methods for satisfying the constraint conditions. Exact methods often require that the …
