Design and Experiment for High Overloading Piezoceramics Actuator Based on Adaptive Munition Available to Purchase

Aimed at the problem that the existing piezoceramics actuator can’t withstand high overloading, based on work principle and high overloading environment of adaptive munition, a high overloading piezoceramics actuator was designed. According to the technologic flow manufactured the piezoceramics actuator sample, innovatively designed the elastic metal frame which is used to precompress piezoceramics actuator, ensured that this actuator has better rigidity and performance of anti-pull and anti-overloading, through the technique criteria demarcation and high overloading experiment of packed actuator to confirm that it has better capability of micro-displacement and anti-overloading, it can’t only satisfy the request of high overloading based on adaptive munition, but also apply to the high overloading micro-nano-actuating field of military defence, aviation and spaceflight etc.
