Using the chip microprocessor DS87C520, a practical miniature pill loading storage test recorder is designed successfully to acquire data in hostile test environments such as high pressure and high shock.

With the joint function of the A/D controller,the high-speed state machine,the phase-delayed clock and the flash memory controller working in the recorder,it can transform the high shock signals into digital ones and store them into the main memory which is made up of flash memory.

A kind of failure mode is observed under high shock experiments.

A high shock resistance plezoelectric gyro is presented in detail,from raising of the subject to fabrication process as well as the key technique measures,and an emphasis on the design and development of the high shock resistance sensing component is placed.

By using optical microscope and SEM,the change in structure and the fracture morphology of a bainitic ductile iron under high-velocity impact were investi-gated.

Tensile properties simulation of two-dimensional woven reinforced composite laminates after high velocity impact;

The failure wave phenomenon was interpreted in glass media under the high velocity impact with the stress levels below the Hugoniot elastic limit.
