Internal resonances in nonlinear vibrations of a continuous rod with microstructure.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
Nonlinear longitudinal vibrations of a periodically heterogeneous rod are considered. Geometrical nonlinearity is described by the Cauchy–Green strain tensor. Physical nonlinearity is modelled expressing the energy of ...
Double pendulum colliding with a rough obstacle.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The externally excited and damped vibrations of the double pendulum in the vertical plane are considered. The pendulum can collide with a rough obstacle many times during its motion. The pendulum is modeled as a piecewise ...
1D model of pulsating flows in pipes dynamics using MOC.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
This paper presents a model of 1D pulsating flows in partially opened pipes.
This is typical of inlet and exhaust pipes of internal combustion engines and piston
compressors. The introduction describes the current state ...
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. ...
Experimental and numerical investigations of a pendulum driven by a low-powered DC motor.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The work is a continuation of numerical and experimental investigations of
a system consisting of a single pendulum with the joint horizontally driven by the use
of a crank-slider mechanism and DC motor. The power supplied ...
On the clutch dynamics with the approximations of resulting contact forces.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The aim of the work is to present effectiveness of numerical simulations of
clutch with frictional contacts, elaborated by some of the current articles in the last
few years. The friction models assumes full developed ...
Identification of a non-linear damping coefficient characteristics in the free decay test of a single pendulum with friction.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
A pendulum in form of an equal arms angle body being a part of
a two degrees-of-freedom mechanical system with friction is identified with
respect to the observed in uence of some resistance of its rotational motion ...
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, ...
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 ...
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 ...
