| Abstract | ||
| This paper suggests a new mechanical design able to harvest dynamic wasted vehicles impact energy by Road- Bumps. Mechanical Speed Bump design is difference the traditional, where it's including many moving parts such as camshaft system, epicyclic gear train system, one way clutch system, flywheel system and generator system. Camshaft system is used to convert liner transient motion into rotational, while epicyclic gear train system is used to convert and control motion. Flywheel system is used to storage an extra energy and generator system is used to convert kinetic energy into electricity. The kinematics and dynamics of motion mechanism and generator are considered. Dynamic model has been derived and analyzed for epicyclic gear train and permanent magnets generator, based on differential equations. Governing differential equations are solved numerically by expression of Duhamel Integral. Results and simulations are carried out to study design features. Design harvested powers are estimated. Guidelines are given to improve this type of energy harvester in future. | ||
