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 ...
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 ...
Vibration Analysis of Collecting Electrodes by means of the Hybrid Finite Element Method
(2014)
The paper presents a hybrid finite element method of shell modeling in order to model collecting electrodes of electrostatic precipitators. The method uses the finite element method to reflect elastic features and the rigid ...
Strain analysis and structural optimization of functionally graded rod with small concentration of inclusions.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The homogenization procedure is applied to strain analysis and optimal
design of a Functionally Graded (FG) rod in the case when the inclusion size is
essentially less than a distance between them. The method is illustrated ...
Influence of position of an anvil beam on vibrations of collecting electrodes.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The paper presents experimentally verified computational model of the collecting electrodes in electrostatic precipitator (ESP). Discretisation of the whole system, both the beams and the electrodes, is carried out by means ...
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 ...
Power consumption analysis of different hexapod robot gaits.
(Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
The paper is focused on the power consumption analysis of different gaits of our constructed hexapod robot controlled by different Central Pattern Generator (CPG) models. There are a lot of gait patterns in the literature ...
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 ...
