Ground vibration test (GVT) is one of the most important procedure in aeroelastic analysis.For the structure might existing nonlinearities which is difficult to characterize,conditioned reverse path (CRP) method provides an effective way to identify both the underlying linear system properties as well as nonlinear coefficients.

In practice,it is usually difficult to obtain the physical model of rotating blade-casing system due to the uncertain nonlinearities.To obviate this problem such to conduct the analysis and design of
The piezoelectric actuators are increasingly popular for high-accuracy and high-speed due to its high resolution,large output force and fast response.However,there is the effect of nonlinear frequency
To the best of authors knowledge,the dynamical behaviors of vibration energy harvesters with fractional derivative damping have not been discussed by researchers using the stochastic averaging method.
In order to improve the convergence of homotopy perturbation technique,we introduce a so-called convergence control parameter into an elegant combination of homotopy perturbation method (HPM) and Lapl
A stochastic averaging method is proposed to study the randomly excited single-degree-of-freedom (SDOF) strongly nonlinear systems with delayed feedback fractional-order PDα controller.
Since the response of a dynamical system to fGn (fractional Gaussian noise) is a non-Markov process and the FPK method cannot be applied to obtain the probability and statistics of the response,we hav
The aim of this paper is to derive the forms of integral transforms of fractional calculus involving Hadamard fractional calculus in some details.The logarithmic convolution (modification of Mellin co
IRVE system has become a hot spot in reentry field due to its large payload ratio,small launch volume and flexible operation.The structural characteristics in severe flight environment need to be stud
A novel crystal format model (CFM) of the rotor system is proposed in the paper.The CFM is made up of crystal grains which are dispersed into a space network structure,and the grain mass and the rotat
This paper proposed a fractional-order colored complex dynamical network model.In this network model,color edges imply that both the outer coupling topology and the inner interactions between any pair
