[Abstract]:Aiming at the technical defects of the road surface generated by piezoelectric transducer, the piezoelectric element suitable for road power generation is selected and the structure is improved. Four protection measures are designed, and the comprehensive performance evaluation index is put forward and the optimal protection structure is determined. The electrical output effect of the typical surface structure combined with small size specimen is evaluated, the energy acquisition entity circuit is developed and the practical application state of the circuit is explored. The results show that the diameter of 35mm and thickness of 0.4mm circular piezoelectric ceramic can meet the technical requirements of power generation pavement. The structure improvement scheme can effectively prolong the service life of piezoelectric elements and the combination of D type rigid copper sheet and rubber pad is the best protection measure type, and the electric output effect of TLC-13 composite power generation road surface is the best. Stable output peak voltage of 14 V, effective output power of 0.44 MW AC electrical signal, standard energy acquisition circuit can efficiently complete the road piezoelectric micro-energy conversion and acquisition function.
