Abstract

The test systems for impact pressure of polyvinylidene fluoride (PVDF) and electrical output characteristics of piezoelectric ceramics were built to study the influence of impact pressure on the electrical output characteristics of PZT-5H piezoelectric ceramics. The one-stage light gas gun is used as a loading means, and the experiments of which the cylindrical aluminum alloy projectiles vertically impact an composite target plate (steel sheet-piezoelectric ceramic-plexiglass) at the speeds of 195 m/s, 487 m/s, 532 m/sand 613 m/s are conducted. The projectile impact on target is analyzed by using ANSYS/LS-DYNA. The time histories of shock pressure of PZT-5H at the different speeds are analyzed. A simplified model of stress wave propagation is established based on the experimental system, and the pressure peak of PZT-5H in the composite structure is calculated by the proposed model. The change rules of PZT-5H piezoelectric ceramics under different peak pressure are analyzed from the time histories of shock pressure, output voltage of piezoelectric ceramics, and charging voltage of energy-storing capacitance. The research results show that the calculated impact pressure peaks are consistent with the simulated and experimental results; the output voltage peak of PZT-5H piezoelectric ceramics rises with the increase in impact pressure peak in the range of pressure peak of 200-700 MPa; the conversion efficiencies of kinetic and electric energies are low when PZT-5H piezoelectric ceramics is impacted by high-speed projectile. As the ratio of energy storage capacity to piezoelectric ceramic capacitance is 5.9∶1, the energy conversion rate of piezoelectric ceramics is 1.1% compared to the primary kinetic energy of projectile.Key
