Abstract:In order to study the electromechanical characteristics of PZT-5H in the temperature range of -40~25℃under the impact loading, the electrostatic parameters of PZT-5H at different temperatures are measured, the liquid nitrogen cooling/Hopkinson mechanical property and piezoelectric ceramic voltage output testing system are built, Hopkinson experiments at different temperatures (-40℃, -25℃, -10℃, 0℃ and 25℃) and different impact velocities are carried out. Experimental results show that , the resistivity and rel… Show more
