  title={Quantification of parametric uncertainties induced by irregular soil loading in orchard tower sprayer nonlinear dynamics},
  author={Americo Cunha and Jorge Luis Psalacios Felix and Jos{\'e} Manoel Balthazar},
Abstract This paper deals with the nonlinear stochastic dynamics of an orchard tower sprayer subjected to random excitations due to soil irregularities. A consistent stochastic model of uncertainties is constructed to describe random loadings and to predict variabilities in mechanical system response. The dynamics is addressed in time and frequency domains. Monte Carlo method is employed to compute the propagation of uncertainties through the stochastic model. Numerical simulations reveals a…

Damage detection in uncertain nonlinear systems based on stochastic Volterra series
An approach based on a stochastic version of Volterra series is proposed to be used in the detection of a breathing crack in a beam vibrating in a nonlinear regime of motion, even in reference condition (without crack).
Numerical and experimental assessment of random matrix theory to quantify uncertainty in aerospace structures
This study utilizes RMT and the Wishart distribution to characterize modal uncertainties that arise due to parametric, non-parametric and experimental variabilities and provides a quantitative bound on the unknown uncertainties that exist within the physical system.


On the nonlinear dynamics of an inverted double pendulum over a vehicle suspension subjected to random excitations
This paper deals with the nonlinear dynamics of a mechanical system which consists of an agricultural tower pulverizer, coupled with a vehicle suspension that is subject to random excitations due to
Computational modeling of the nonlinear stochastic dynamics of horizontal drillstrings
A beam theory, with effects of rotatory inertia and shear deformation, is considered, which is capable of reproducing the large displacements that the beam undergoes, which generate phenomena such as bit-bounce, stick-slip, and transverse impacts.
Non-linear dynamics of a tower orchard sprayer based on an inverted pendulum model
A modern form of air-assisted orchard sprayer consists of a vertical structure, or tower fitted with spray nozzles assisted by fans. The sprayer travels between crop rows and the tower is either
On the nonlinear stochastic dynamics of a continuous system with discrete attached elements
The dynamic behavior of the bar is significantly altered when the lumped mass is varied, becoming, on the right extreme and for large values of the concentrated mass, similar to a mass-spring system.
Karhunen–Loève decomposition of coupled axial/bending vibrations of beams subject to impacts
Abstract This work presents a study of the oscillations of a vertical slender beam, clamped in its upper extreme, pinned in its lower one and constrained inside an outer cylinder in its lower
A comprehensive overview of a non-parametric probabilistic approach of model uncertainties for predictive models in structural dynamics
Abstract In structural dynamics, a predictive model is constructed by developing a mathematical–mechanical model of a designed system in order to predict the response of the real system which is the
Quantification of the influence of the track geometry variability on the train dynamics
In a context of increasing interoperability, several high speed trains are likely to run on the same tracks, whereas they have been originally designed for specific railway networks. Due to different
Stochastic modeling of uncertainties in computational structural dynamics—Recent theoretical advances
This paper deals with a short overview on stochastic modeling of uncertainties. We introduce the types of uncertainties, the variability of real systems, the types of probabilistic approaches, the

Abstract The Karhunen–Loeve (KL) decomposition establishes that a 2D random field can be expanded as a series involving a sequence of deterministic orthogonal functions with orthogonal random
