In this paper, we used the automatic turning of photovoltaic cells in order to find the sun's position and gain energy and therefore save it in batteries. In order to enhance the battery saving ability, Lithium titanate nanoparticles in the anode of lithium batteries have been investigated. Recently, the demand for structural safety subjected to impact loading has escalated. As a consequence, various studies for predicting the behavior of structures under impact loading have been conducted. In this paper, transverse and longitudinal drop weight impact tests on a beam has been analyzed. Consideration is given to the vibration response of the beams with rectangular, circular, and I-beam cross sections. Different boundary conditions (i.e. Fixed-Fixed). Also, in order to use the maximum waste vibration, we used PZT-۵ to enhance harvested energy.
