2. Masses and inertias related to the motor or wheel
Depending on the problem to be solved or the type of modeling to be used (engine or vehicle vision), we may need to reduce the rotating inertia to the primary (i.e. the crankshaft) or the wheel, or even calculate the equivalent translational inertia (or mass) of the drive train.
2.1 Equivalent translational mass of the drive train
The rotating inertia of the motor (index m), the drive train (index sb) and the wheels (index r) can be converted into an equivalent translational mass m eq . Figure 13 shows the cascade of rotating masses from the motor to the wheels (rolling configuration).
