Read moreWhat does natural frequency mean?
A natural frequency is defined as that frequency at which a body will vibrate if excited by an external force .
Read moreWhat is the natural frequency of a steel beam?
For lightweight structures with span above 8 m (24 ft) vibrations may occur. In general – as a rule of thumb – the natural frequency of a structure should be greater than 4.5 Hz (1/s) .
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.
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.
