Özet:
In recent years, due to the
increase in carbon emissions and the effects of fossil-fuel vehicles on climate
change, electric vehicles are also becoming popular for public transportation.
The use of electric vehicles drives the adoption of new technologies and
underscores the need for classical mechanical systems to become electronic and
operate more efficiently and effectively. Given the fuel consumption of public
transportation vehicles, energy efficiency becomes even more important.
Switching to electric vehicles in public transportation raises the issue of
energy recovery to increase efficiency. The damper in the suspension system
generally creates a damping force by limiting hydraulic flow in the bump and
rebound directions. The damped energy becomes idle without being harvested due
to heating of the hydraulics inside the damper and the damper itself, and the
subsequent release of this heat to the environment. An electric-motor damper
design that can be used for energy harvesting instead of a standard hydraulic
damper enables harvesting idle energy here. In this research, a quarter-vehicle
model was implemented in MATLAB to calculate the working forces of the damper
element in the front suspension of a public transport vehicle. While
calculating the damper element's forces, the force values were not treated as
constants but varied with damper speed and direction, creating a model better
suited for real use.
