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 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.
