Occurrence of strick-slip phenomenon.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007)
A self-excited system wit h unilateral friction contact modelled by a two degrees-of-freedom mechanical system, where the normaI farce varies during displacement of a block has been studied. The constructed real laboratory ...
Asymptotic study of elastic half-plane with embedded punch.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007)
A contact problem for an elastic half-plane and an embedded rigid punch is studied. The employed mathematical model describes the behavior of a soil with embedded foundation. The analytical solution geverning the stress ...
The finite element model of the human rib cage.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007)
In the paper, finite element analysis of the rib cage model is applied to recognize stress distributions and to determine the rate of bone fractures (especially for pathologically changed bones). Two thorax models are ...
The triple pendulum with barriers and the piston - connecting rod - cranckshaft model.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007)
A model of a flat triple pendulum with obstacles imposed on its position is used for the modelling of a piston-connecting rod-cranks haft system of a mono-cylinder four-stroke combustion engine. The introduced self-excited ...
Analysis of stability of the human gait.
(Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007)
Analysis of the gait stability of a man moving along an even surface with a constant velocity is presented. The stability criteria applied to biped robots, namely: the Zero Moment Point (ZMP) and the Ground projection of ...
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 ...
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 ...
