How to find the fundamental frequency of the component(let it for engine)?
How the orders of that frequency is approximated while FEA?
How the orders of that frequency is approximated while FEA?
The fundamental frequency in vibration is the lowest frequency at which an object can vibrate, creating a standing wave pattern. It is also known as the first harmonic and is determined by the physical properties of the object, such as its size, shape, and material.
The fundamental frequency can be measured by using a frequency analyzer or a tuning fork. A frequency analyzer is a device that measures the different frequencies present in a vibration, while a tuning fork is a metal object that produces a specific frequency when struck against a surface.
The fundamental frequency is the same as the natural frequency of an object. The natural frequency is the frequency at which an object will vibrate most easily and with the greatest amplitude. For a system with a single degree of freedom, the natural frequency is equal to the fundamental frequency.
The fundamental frequency determines the pitch of the sound produced by an object. Objects with a higher fundamental frequency will produce higher-pitched sounds, while objects with a lower fundamental frequency will produce lower-pitched sounds. This is because the frequency of a sound wave is directly related to its perceived pitch.
Yes, the fundamental frequency can be changed by altering the physical properties of the object, such as its length, tension, or density. For example, plucking a guitar string at different points along its length changes the fundamental frequency and produces different notes. Additionally, adding external forces, such as damping or resonance, can also change the fundamental frequency of an object's vibration.
