Abstract

The invention discloses a force-electricity coupling dynamic fracture experimental system in the technical field of mechanical structural deformation and mechanical experiments. The force-electricity coupling dynamic fracture experimental system is used for realizing experimental studies on fracture characteristics of piezoelectric and ferroelectric materials under a dynamic force-electricity coupling load field. The system comprises a dynamic mechanical load loading unit, a dynamic pulse electric load loading unit, an insulation supporting protection unit, a dynamic control unit, a data collection unit and a data processing unit. The dynamic mechanical load loading unit is connected with the insulation supporting protection unit which is connected with an experimental specimen which is connected with the dynamic pulse electric load loading unit, and the dynamic control unit is respectively connected with the dynamic mechanical load loading unit, the dynamic pulse electric load loading unit and the data collection unit which connected with the data processing unit. The force-electricity coupling dynamic fracture experimental system provides an effective guarantee for dynamic fracture performance tests of piezoelectricity and ferroelectricity.

Description

technical field [0001] The invention belongs to the technical field of mechanical structure deformation and mechanical experiments, and in particular relates to a mechanical-electrical coupling dynamic fracture experimental system. Background technique [0002] Piezoelectric materials and ferroelectric materials have special piezoelectric and dielectric properties, and are widely used in modern science and technology, from power electronics, aerospace, nuclear energy engineering, to robotic intelligent systems, information storage systems, and intelligent sensing systems, etc. All fields play an important role. On the one hand, piezoelectric ferroelectric materials are often subjected to dynamic mechanical loads and dynamic pulse electric loads during service. In terms of dynamic mechanical loads: typical US-Russian nuclear weapons, high-power microwave weapons, and conventional weapon warheads trigger fuzes, using explosives Shock waves are generated by means of explosions...
