Mobility method: principle
The mobility method consists in describing the mechanical system using the indirect analogy, which is easy to do, then converting the electronic circuit into the direct analogy.
there are three stages:
Description of the system by its complete mechanical schematic.
Obtaining the electrical circuit in the indirect analogy (topology of the mechanical schematic "respected" by the indirect analogy)
Conversion to a "dual circuit" to obtain the electrical circuit in the direct analogy.
This method can be used for complex mechanical systems.
