Random response of a simple system with stochastic uncertainty and noise in parameters

Autor: Náprstek J., Fischer C.

Publikováno v: Applied and Computational Mechanics, Vol 15, Iss 2, Pp 185-196 (2021)

The paper is concerned with the analysis of the simultaneous effect of a random perturbation and white noise in the coefficient of the system on its response. The excitation of the system of the 1st order is described by the sum of a deterministic si

Semi-analytical stochastic analysis of the generalized van der Pol system

Autor: Náprstek J., Fischer C.

Publikováno v: Applied and Computational Mechanics, Vol 12, Iss 1, Pp 45-58 (2018)

The paper is motivated by a series of wind tunnel experiments, which deal with aeroelastic Single Degree of Freedom (SDOF) and Two Degrees of Freedom (TDOF) section models. Most of them can be mathematically expressed by van der Pol-Duffing type equa

Dynamics of beam pair coupled by visco-elastic interlayer

Autor: Náprstek J., Hračov S.

Publikováno v: Applied and Computational Mechanics, Vol 9, Iss 2, Pp 127-140 (2015)

An exact method is presented for solving the vibration of a double-beam system subjected to harmonic excitation. The system consists of a loaded main beam and an auxiliary beam joined together using massless visco-elastic layer. The Euler-Bernoulli m
