Direct approach: mechanical electrical analogy (1/2)
When using the direct analogy, the equivalent electrical network can be obtained by applying the following rules, which are based on the principles of this analogy:
A loop, describing the fundamental principle of dynamics applied to a moving mass, corresponds to the degree of freedom associated with this mass.
This loop is a closed circuit, with all the elements associated with the movement of the mass (including the applied exterior forces), in series.
The coupling between the two degrees of freedom is represented by a branch that links the two loops. There are therefore three branches in parallel.
