nounfemininepl: eigenfrequencies
frequência própria
1. The natural frequency at which a system oscillates when disturbed from its equilibrium position and allowed to vibrate freely without external driving forces
The eigenfrequency of the bridge was calculated to ensure it wouldn't resonate with wind vibrations.
A frequência própria da ponte foi calculada para garantir que não entrasse em ressonância com vibrações do vento.
2. In mathematics and physics, a characteristic frequency associated with an eigenmode of a vibrating system
Each mode of vibration has its own eigenfrequency determined by the system's mass and stiffness.
Cada modo de vibração tem sua própria frequência própria determinada pela massa e rigidez do sistema.
3. The frequency corresponding to an eigenvalue in the analysis of oscillatory systems
The first eigenfrequency represents the lowest natural frequency of oscillation.
A primeira frequência própria representa a mais baixa frequência natural de oscilação.
This is a specialized technical term primarily used in engineering, physics, and mathematics disciplines in both Brazil and the United States. It is essential in structural engineering, mechanical engineering, and vibration analysis. The term is universally understood in academic and professional engineering contexts across both countries.
