Read moreHow many natural frequencies does a system have?
An infinite number . The number of natural frequencies an object can have depends on its flexibility in different directions and degrees of freedom. In any one direction it can have one fundamental mode and many harmonics.
Read moreWhy does a system have a natural frequency?
All stable, unforced, mechanical systems vibrate harmonically at certain discrete frequencies , known as natural frequencies of the system. A system with three masses would have three vibration frequencies, and so on. In general, a system with more than one natural frequency will not vibrate harmonically.
Read moreWhat is natural frequency and why is it important?
When an object vibrates at a frequency equivalent to its natural frequency, the vibration of the amplitude increases significantly which could lead to irreparable damage , therefore, it is important to know the natural frequency.
Read moreWhat is the body’s natural frequency?
According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz , and the frequency of a sitting posture in the cab is generally 4–6 Hz. The natural frequency of the main body parts is shown in Table 1.
