ANALYSIS OVERVIEW

Single Degree of Freedom Vibration

To understand why vibration analysis is useful and what it entails, we must first think of
a simple mass spring damper model shown in Figure 14.

Figure 14: A simple single-degree-of-freedom system is represented where m is the mass, k is the
spring constant, c is the damping coefficient, x represents the displacement from equilibrium and
f defines the force acting on the mass as a function of time.

As review, some simple equations which describe the motion of this system and define
key parameters are listed in Table 1. For those that are unfamiliar, there are plenty of
