kényszeroszcillációról

Kényszerrezgés refers to the phenomenon of forced oscillation in physics. It occurs when an external periodic force is applied to a system that is capable of oscillating. Without the external force, the system would naturally oscillate at its own characteristic frequency, known as the natural frequency. However, when driven by an external force, the system is compelled to oscillate at the frequency of that applied force.

The amplitude of the forced oscillation depends on several factors. A crucial aspect is the relationship between the driving frequency and the natural frequency of the system. When the driving frequency is close to the natural frequency, a phenomenon called resonance occurs, leading to a significantly large amplitude of oscillation. This is because the energy is transferred most efficiently from the driving force to the oscillating system.

Damping also plays a vital role. In a real-world system, energy is always dissipated due to friction or other resistive forces. Damping reduces the amplitude of the forced oscillations, especially near resonance. A heavily damped system will exhibit a much smaller amplitude even at resonance compared to a lightly damped system. The presence of damping prevents the amplitude from becoming infinitely large at resonance. The study of kényszerrezgés is fundamental to understanding many physical phenomena, from the behavior of mechanical structures under external forces to the response of electrical circuits to alternating currents.
