detuned coupling
[dɪˈtjuːnd ˈkʌplɪŋ]
nounpl: detuned couplings
acoplamento dessintonizado
1. A coupling mechanism in engineering or physics where the resonant frequency or operational frequency is intentionally adjusted away from its natural or designed frequency to reduce energy transfer, minimize vibration, or prevent unwanted interactions between connected systems
The detuned coupling in the transmission system reduced harmful vibrations that were affecting machine performance.
O acoplamento dessintonizado no sistema de transmissão reduziu as vibrações prejudiciais que estavam afetando o desempenho da máquina.
2. In RF (radio frequency) and microwave engineering, a coupling structure that has been deliberately shifted from its optimal frequency response to achieve specific impedance matching or signal isolation characteristics
Engineers designed a detuned coupling to isolate the two circuits while maintaining acceptable signal levels.
Os engenheiros projetaram um acoplamento dessintonizado para isolar os dois circuitos mantendo níveis de sinal aceitáveis.
This is a specialized technical term primarily used in mechanical engineering, electrical engineering, and physics disciplines. It is not commonly used in everyday conversation in either Brazilian Portuguese or English-speaking regions. The term is standardized in technical and academic documentation across both countries.
