Resumen

The complex nonlinearities of hypersonic vehicles can lead to strong couplings between variables, which will bring great challenges to flight control. For this purpose, this paper proposes a novel coupling analysis method for the longitudinal dynamics of a hypersonic vehicle, based on which a coordination controller is designed to reduce the negative effects of the couplings. Initially, according to the coupling characteristics of the hypersonic vehicle, a novel coupling analysis method based on the dynamic equations is proposed to describe the dynamic coupling relationships between variables.

Resumen

Diaphragm couplings are prone to developing diaphragm cracks under prolonged high-speed operating conditions, which can lead to degradation in the performance of the transmission system and affect the dynamics of the shafting system. To investigate the effects of diaphragm cracks on the dynamics of couplings and the shafting system, a finite element model of a diaphragm coupling with a crack failure is established using ANSYS finite element software to analyze the time-varying characteristics of the diaphragm coupling’s angular and radial stiffness. A shaft dynamics model of the diaphragm coup

This paper synthesizes a swing-type flexible coupling (STFC) utilizing robotic kinematics' Denavit-Hartenberg (DH) nomenclature. The study aimed to design a coupling for dynamic misalignments to maintain efficient torque transmission for applications like robotics, automotive engineering, and industrial machinery. Links are defined by joint angle, offset, length, and twist in DH notation, simplifying multi-link mechanical systems.

Resumen

In this paper, we analyze how the behavior of a chaotic dynamical system changes when we couple it with another. We focus our attention on two aspects: the possibility of chaos suppression and the possibility of synchronization. We consider a Symmetric Linear Coupling and several free dynamics. For each of them we study the evolution of the coupling behavior with the coupling strength constant, defining windows of behavior. We extend the analysis to some other couplings. This is a survey paper.

Resumen

The highly nonlinear and coupling characteristics of a flexible air-breathing hypersonic vehicle create great challenges to its flight control design. A unique parameter adaptive nonsingular terminal sliding mode method is proposed for longitudinal control law design of a flexible coupling air-breathing hypersonic vehicle. This method uses adaptive reaching law gain instead of the additional adaptive compensation term to handle the uncertainty to improve robustness. The stability of the close loop system is proved via a Lyapunov way. The longitudinal tracking control law for velocity and angle

Resumen

The development of accurate impact dynamics models in rotating machinery with spline couplings is a challenging problem that demands special attention. The dynamic behavior of the system is highly dependent on the spline coupling stiffness, which is nonlinear under different loads. To address this challenge, rotor dynamics models that incorporate spline couplings have been developed. In this paper, firstly, the mechanical model of spline coupling considering large deformation under different loads is established and verified by finite element software. Furthermore, a spline rotor dynamics mode

In recent years, most studies of complex networks have focused on a single network and ignored the interaction of multiple networks, much less the coupling mechanisms between multiplex networks. In this paper we investigate synchronization phenomena in multilayer networks with nonidentical topological structures based on three specific coupling mechanisms: assortative, disassortative, and anti-assortative couplings. We find rich and complex synchronous dynamic phenomena in coupled networks. We also study the behavior of effective frequencies for layers I and II to understand the underlying mic

Resumen

One of the ways to reduce dynamic loads in machine drives is the use of couplings with low torsional stiffness. When the torque is transmitted by the coupling, the elastic elements deform, increasing the time of energy transfer from one coupling half to another, thereby reducing dynamic loads. The lower the stiffness of the coupling, the less dynamic loads. If a coupling with serpentine springs is used to reduce stiffness, instead of a single spring, a package of such springs should be used, the cross-sectional dimensions of which are the same as the cross-section of a single spring.

We introduce a model to mimic the dynamics of oscillators that are coupled by mean-field nonlinear memductance.

Specifically, depending on the forcing frequency and coupling strength, we find anti-phase and intermittent synchronization.

Resumen

Based on the Lagrange equation, the linear and nonlinear dynamic models of straddle monorail pantograph considering the lateral vibration of bogie are derived. On this basis, the lateral coupling dynamic model of pantograph-catenary is established. Newmark method is used to solve the pantograph-catenary coupling dynamic model. In order to evaluate the applicability of the two models，this paper analyzed the contact force response of two model with different speeds.

An appropriate dynamic coupling form between nodes and edges’ state can effectively promote the emergence of desired network function (phenomenon), but the existing literatures have not conducted in-depth research on the coupling mechanism. This paper mainly focuses on the coupling auxiliary mechanism of dynamic edges for the emergence of cluster phenomenon of nodes, explores the essential relation between structure and function in complex dynamical networks (CDNs). Firstly, a novel model of CDNs has dynamic systems attached on not only nodes but also edges is proposed from the viewpoint of la

Resumen

This work presents a nonlinear dynamic model considering the multi-tooth meshing behaviour and mass eccentricity of an involute spline coupling to tackle the serious problem of involute spline failure, in aviation power transmission systems. The dynamic meshing force is calculated for the same. Based on this, the influence of different mass eccentricities on the nonlinear dynamic response of the spline coupling was investigated in aero-engines. The results show that when the mass eccentricity is small, its impact on the system is insignificant. When the eccentricity reaches a certain value, th

Resumen

Spin pumping and angular momentum transfer, i.e., the emission of a spin current by a precessing magnetization and the reverse process of absorption, play an important role in coherent magnetic dynamics processes in multilayered structures. For ferromagnetic layers separated by a nonmagnetic interlayer these effects give rise to a dynamic coupling between the layers that is dissipative in nature and affects the damping of coherent magnetization precession. We have used micromagnetic simulations to analyze the influence of such a dynamic coupling on the propagation of a laser-induced surface ma

Resumen

The dual-axis drive mechanism of satellite antenna as a typical multi-joint aerospace mechanism consists of azimuth axis and pitch axis. The multi-clearance contained within those drive joint cause contact and impact in joint, and consequently affect the dynamic positioning accuracy. A nonlinear dynamic model of planetary gears with multiple clearances couplings is proposed to investigate the influence mechanism of clearances on the dynamic performances. The nonlinear factors such as radial clearance, backlash and time-varying meshing stiffness of the bearing are considered in the model. And t

Recently, methods have been developed to analyse couplings in dynamic systems. In the field of medical analysis of complex cardiovascular and cardiorespiratory systems, there is growing interest in how insights may be gained into the interaction between regulatory mechanisms in healthy and diseased persons. The couplings within and between these systems can be linear or nonlinear. However, the complex mechanisms involved in cardiovascular and cardiorespiratory regulation very likely interact with each other in a nonlinear way.

The impact dynamics of spatial multi-link flexible multibody system is studied based on the continuous contact force method (CCFM). According to the rigid-flexible coupling dynamic theory of flexible multibody system, the rigid-flexible coupling continuous dynamic equations of the system are established by using the recursive Lagrange method. The impact dynamic equations of the system are stylized derived on the use of CCFM basing on the nonlinear spring-damper model.

Abstract In the rigid-flexible coupled structure, the coupling between the elastic deformation motion of the flexible structure and the wide range of the rigid body motion will make the dynamic behaviour of the structure more complicated. This paper established a class of rigid body structures with flexible attachments as a rigid body-cantilever beam coupling model. The nonlinear dynamic equations of the structure are established by taking the dynamic stiffening into consideration. The dynamic responses of the structures are obtained by numerical simulations.

Resumen

A simple formula is proposed to estimate the Statistical Energy Analysis (SEA) coupling loss factors (CLFs) for two flexible subsystems connected via discrete interfaces. First, the dynamic interactions between two discretely connected subsystems are described as a set of intermodal coupling stiffness terms. It is then found that if both subsystems are of high modal density and meanwhile the interface points all act independently, the intermodal dynamic couplings become dominated by only those between different subsystem mode sets. If ensemble- and frequency-averaged, the intermodal coupling s

Based on the modified Maxwell-Wagner model, the molecular dynamics method is applied to simulate the three-dimensional structural changes of the electrorheological (ER) fluids in an electric field and a poiseuille flow field. And it is analyzed that the structure-force dynamic coupling is characterized significantly by capture effect. The simulation results show that: when the electric field is applied, a chain network will capture the upstream particles in the flow field causing the local electric field force changed.
