The study of buffer structure of on-board test´s circuit module in high shock

In order to measure the acceleration of a projectile penetrating hard aims, we adopt on-board test technology. When the projectile penetrates hard targets, such as concrete, rock, and metal targets, the on-board test´s circuit module suffers very high shock. After having analyzed related technology references, and compared different kinds of buffer materials and structures, we performed some experiments, then drew the conclusion that it is a valid method to use nonlinear buffer structures, such as plastic springs, to absorb the energy of the on-board test circuit module in the process of the buffer structure´s compressive collapse.
