The aim of this paper is to provide a theoretical analysis on the mechanical power of the mass spring’s system. Some tests are conducted to experimentally evaluate the theoretical analysis and to investigate the mechanical energy ability of this concept. | Mathematical modeling of mass spring s system Hybrid speed bumps application for mechanical energy harvesting Engineering Solid Mechanics 7 2019 47-58 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Mathematical modeling of mass spring s system Hybrid speed bumps application for mechanical energy harvesting Chouaib Ennawaouia b Houda Lifia c Abdelowahed Hajjajia Abdessamad Elballoutia Said Laasria and Az-eddine Azima b a Laboratory of Engineering Sciences for Energy National School of Applied Sciences El Jadida UCD 24000 El Jadida Morocco b Laboratory of Mechanics and Energy Faculty of Sciences El Jadida UCD 24000 El Jadida Morocco c Laboratory of Physics and Nuclear Atomic and Molecular Techniques Faculty of Sciences El Jadida UCD 24000 El Jadida Morocco A R T I C L EI N F O ABSTRACT Article history The aim of this paper is to provide a theoretical analysis on the mechanical power of the mass Received 10 September 2018 spring s system. Some tests are conducted to experimentally evaluate the theoretical analysis and Accepted 5 November 2018 to investigate the mechanical energy ability of this concept. The authors suggest a system used for Available online applications of energy harvesting from roads. The system is able to transform the kinetic energy 5 November 2018 Keywords produced by the passage of vehicles on the road for electrical energy based on the mass-spring Energy harvesting using two technologies. The hybrid system has two goals. First supply the entourage by a Mass-spring mechanism to produce significant electrical power used mainly for public lighting. A device is also Hybrid system provided for storing electrical energy for later use for home lighting at night or in the case of bad Mechanical system weather. Second the piezoelectric subsystem controls the spring s health through analyzing the Piezoelectric polymers amplitude and shape of the voltage generated by a piezoelectric material. .
