Combustion Process in a Spark Ignition Engine: Analysis of Cyclic Maximum Pressure and Peak Pressure Angle
G. Litak, T. Kaminski, J. Czarnigowski +2
In this paper we analyze the cycle-to-cycle variations of maximum pressure and peak pressure angle in a four-cylinder spark ignition engine. We examine the exp…
Response of a Magneto-Rheological Fluid Damper Subjected to Periodic Forcing in a High Frequency Limit
Marek Borowiec, Grzegorz Litak, Rafal Kasperek
We explored vibrations of a single-degree of freedom oscillator with a magneto-rheological damper subjected to kinematic excitations. Using fast and slow scales decoupling procedur…
Stochastic description of the deterministic Ricker's population model
Arkadiusz Syta, Grzegorz Litak
We adopt the '0-1' test for chaos using Brownian motion chains to identify the dynamics of the Ricker's population model. In the '0-1' test '0' is related to regular motion while '…
Homoclinic transition to chaos in the Ueda oscillator with external forcing
Grzegorz Litak, Arkadiusz Syta, Marek Borowiec
We examine the Melnikov criterion for transition to chaos in case of a single degree of freedom nonlinear oscillator with the Ueda well potential and an external periodic excitatio…
Phase lock and rotational motion of a parametric pendulum
Grzegorz Litak, Marek Borowiec, Marian Wiercigroch
The effect of noise on a rotational mode of a pendulum excited kinematically in vertical direction has been analyzed. We have shown that for a weak noise transitions from oscillati…
Wavelet Analysis of Cycle-to-Cycle Pressure Variations in an Internal Combustion Engine
Asok K. Sen, Grzegorz Litak, Rodolfo Taccani +1
Using a continuous wavelet transform we have analyzed the cycle-to-cycle variations of pressure in an internal combustion engine. The time series of maximum pressure variations are…
Vibration of the Duffing Oscillator: Effect of Fractional Damping
Marek Borowiec, Grzegorz Litak, Arkadiusz Syta
We have applied the Melnikov criterion to examine a global homoclinic bifurcation and transition to chaos in a case of the Duffing system with nonlinear fractional damping and exte…
Transition to Chaos in the Self-Excited System with a Cubic Double Well Potential and Parametric Forcing
Grzegorz Litak, Marek Borowiec, Arkadiusz Syta +1
We examine the Melnikov criterion for a global homoclinic bifurcation and a possible transition to chaos in case of a single degree of freedom nonlinear oscillator with a symmetric…
Pulsive feedback control for stabilizing unstable periodic orbits in a nonlinear oscillator with a non-symmetric potential
G. Litak, M. Ali, L. M. Saha
We examine a strange chaotic attractor and its unstable periodic orbits in case of one degree of freedom nonlinear oscillator with non symmetric potential. We propose an efficient…
Chaotic Vibration of a Quarter-Car Model Excited by the Road Surface Profile
Grzegorz Litak, Marek Borowiec, Michael I. Friswell +1
The Melnikov criterion is used to examine a global homoclinic bifurcation and transition to chaos in the case of a quarter car model excited kinematically by the road surface profi…
