Investigation of vibration parameters of the freight cars is presented. Several designs of piezoelectric energy harvester are proposed for the efficient conversion of mechanical vibrations into electrical power. Based on experimental studies a comparison of different types and designs of energy harvester is performed. The amount of energy required for wireless transceiver for monitoring location of a vehicle is evaluated. Obtained data can be used for development of production technology of the piezoelectric energy harvester to provide autonomous power supply for freight cars.
