Model of the gas journal bearing dynamics with a exibly supported foil.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The work is devoted to an analysis of the journal bearing dynamics
employing a numerical model which takes into account factors related to
motion and friction of non{rotating elements of the sleeve. This model yields
the ...
Modelling and numerical simulations of a pendulum elastically suspended and driven by frictional contact with rotating disk.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The work concerns modelling and numerical simulations of a special kind of physical pendulum frictionally driven. The pendulum’s joint is suspended elastically in the plane of the motion resulting in the full plane motion ...
Mathematical model of a multi-parameter oscillator based on a core-less three-phase linear motor with skewed magnets.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
This paper uses the example of a three-phase core-less linear motor to create
a mathematical model of single-dimension multi-parameter oscillator. The studied
linear motor consists of: a stator, an U-shaped stationary ...
Mathematical model of pennate muscle.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The purpose of this study is to create a new mathematical model of pennate striated skeletal muscle. This new model describes behaviour of isolated flat pennate muscle in two dimensions (2D) by taking into account that ...
Dynamics simulations of a rigid body lying on a vibrating table with the use of special approximations of the resulting contact forces.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The work presents simulations and dynamics of a rigid body lying on a
vibrating table. An attempt of shaping and control the body dynamical behavior, by
the use of manipulation of parameters of the table oscillations, ...
Simulating the damped vibrations of a fractional oscillator with fuzzy initial conditions.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
A Picard-like scheme using quadrature and differential quadrature
rules, formerly introduced to solve integro-differential equations, is herein adapted
to solve the problem of an oscillator with damping defined by the ...
Theoretical analysis of the foil bearings dynamic characteristics.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
In the theoretical analysis, three systems were identified: a rotor, a
gas film and a exible structure. The mathematical analysis involves formulation of analytical equations for each of these elements and determination ...
Mechanical systems with two nonlinear springs connected in series.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The aim of the paper is analysis of dynamical regular response of the
nonlinear oscillator with two serially connected springs of cubic type nonlinearity. Behaviour of such systems is described by a set of differential-algebraic ...
Axially excited spatial double pendulum nonlinear dynamics.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
Analysis of a 3D spatial double physical pendulum system, coupled by two
universal joints is performed. External excitation of the mechanism is realized
by axial periodic rotations of the first joint of the pendulum. ...
On the vibrations of a composite structure with hexagonal structure of a circular inclusions.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
One of the major advantages of homogenization is a possibility of the
generalization of the obtained results. Namely, if a solution to the local problem is found, then without principal problems one may solve not only the ...
