![]() ![]() The mass is an inertial element and equivalent to an inductance. The damper acts as a dissipative element and is equivalent to a resistor. Consider a mass-spring-damper system, where the spring acts as a storage element and is equivalent to a capacitor in an electrical circuit. Let’s discuss the electrical analogy in little more detail. These kinds of analogies are very helpful when defining electromechanical systems, since such systems have a connection between electrical and mechanical parts. The impedance analogy makes the force and voltage analogous, whereas mobility makes velocity and current analogous. Numerous analogies are theoretically possible, but two analogies are widely used: impedance and mobility.įor a mechanical system, impedance is the ratio of force and velocity, whereas mobility is the ratio of velocity and force (=1/impedance). These analogies are developed to find a relationship between identical mathematical variables used in mechanical and electrical physics.
