WebSpring Frequency Calculator to calculate natural frequency of a spring with a weight at lower end. Spring is fixed from upper end and the lower end is free. Natural frequency of spring mass system formula is f1=12π√kM f 1 = 1 2 π k M . … A modal analysis calculates the frequency modes or natural frequencies of a given system, but not necessarily its full-time history response to a given input. The natural frequency of a system is dependent only on the stiffness of the structure and the mass which participates with the structure (including self-weight). It is not dependent on the load function. It is useful to know the modal frequencies of a structure as it allows you to ensure that the frequ…
