Optimization method of pavement piezoelectric energy harvesting system

Abstract

The invention provides an optimization method of a pavement piezoelectric energy harvesting system. According to the method, a plurality of parameters influencing a piezoelectric energy harvesting effect are combined into a plurality of dimensionless parameters in a dimensionless processing mode, so that a relation change curve among the dimensionless parameters is obtained, and a strategy for optimizing an energy harvesting system is obtained by analyzing a curve change trend. According to the method, the traditional energy harvesting optimization analysis is simplified, the workload is reduced, meanwhile, the mutual relation between all parameters can be discussed more easily, the intrinsic relation in the system can be mastered more comprehensively, and the method has certain guiding significance and engineering application value for the optimization design of the energy harvesting system in actual engineering.
