Research on implementation of harvester on the cargo wagon

Abstract

This paper is dedicated to theoretical modelling of operation of piezoelectric harvester on the frame of railway car go wagon. Data of wagon vibration is taken from real data of wagon frame vertical vibrat ion from drive with velocities 40 km/h and 60 km/h. For this research of membrane type pie zoelectric harvester special dynamic model was built. Membrane of harvester was transfor med into circular cross-section beams with different cross section areas, using cer tain limitations and assumptions in the model. For this dynamic model equations of movement were built using special methodology. Transformed into operator form system equations solved using Simulink and resulting amplitudes of vibration and energies were obtained. On given results and observed phenomena conclusions are drawn.
