تعريف natural frequency في الإنجليزية الإنجليزية القاموس.
The frequency of free vibration of a system The frequency at which an undamped system with a single degree of freedom will oscillate upon momentary displacement from its rest position
1 The frequency of free oscillation of a system For a multiple-degree-of-freedom system, the natural frequencies are the frequencies of the normal modes of vibration
A projecting aperture at the end of a tube, pipe etc serving as an outlet for compressed air Reduces the demand on the compressor by generating the highest thrust and volume for the lowest possible air consumption (099)
the frequency of oscillation that, once begun, will continue without a driving force if no damping forces are present
The frequency of vibration or oscillation which a system (anything from a road bridge to an violin string) will inherently adopt according to its structure given a suitable excitation, such as a gale force wind or a bow Also called the normal mode
(MRI) The frequency at which an object or system oscillates when not subjected to a continuous or repeated external force When an object is forced to oscillate at this frequency the amplitude of the oscillation will increase dramatically
A frequency at which an elastic object, once energized, will vibrate Minimum energy is required to continue vibration at that frequency Also called resonant frequency
The frequency at which a particular object or system vibrates when pushed by a single force or impulse, and not influenced by other external forces or by damping If you hold a slinky by one end and let it hang down and then give it one push up from the bottom, the rate of up-and-down motion is its natural frequency
The frequency that an object vibrates the easiest at An example is a piano tuning fork or an open ended hand wrench A microwave oven vibrates water molecules at their natural frequency, 2 4GHz, to get them to vibrate and heat up The natural frequency of automotive suspension systems has typically been between 10 and 15 Hz; however, later suspension designs have raised the frequency to 20 - 25 Hz
The frequency of free (not forced) oscillations of the sensing element of a fully assembled transducer *
The frequency of an undamped system's free vibration; also, the frequency of any of the normal modes of vibration Natural frequency drops when damping is present
A frequency at which an elastic object naturally tends to vibrate, so that minimum energy is required to produce a forced vibration or to continue vibration at that frequency
As an example, strings of differing thickness, tension or length will make a different sound when they vibrate This is because the different strings vibrate at a different rate or frequency Each different string will vibrate at its own natural frequency Typically a long fat string will have a low Natural Frequency and a short thin string will have a higher Natural Frequency Hence an instrument designed to make low deep sounds is typically large as is the Bass So this instrument is designed to have a low Natural Frequency This is also true for light but with light you see different colours rather than hear different sounds So what I am getting at is that everything has a Natural Frequency Including trees, poles, buildings, electrical components and body parts
