The Theoretical Research about the Piezoelectric Materials Generating Capacity on Road

This article determine the wheel load on the role of piezoelectric vibrator in the way as the low-frequency vibration force through analyzing the wheel load, and the loading frequency is 10Hz;in this paper, combining with asphalt roadbed structural response, we get that the piezoelectric conversion device that between the above layer and the middle layer generate optimal performance adopting the theoretical calculation, a single piezoelectric vibrator can generate the electricity by a 2.62 mJ, what provides a theoretical support for the pavement performance of the piezoelectric material.
