Abstract

The invention discloses a pneumatic type high acceleration vertical impact table, which mainly comprises a support frame, a impact cylinder, a piston assembly, a buffer mechanism, a piston limiting release mechanism and the like. The working process of the pneumatic type high acceleration vertical impact table is as follows: the piston assembly is assembled in the impact cylinder, and a piston is locked and limited by the piston limiting release mechanism, and then, the impact cylinder is rotated in a vertical status and well fixed, and the impact cylinder is inflated until reaching a setting pressure; the locking of the piston by the piston limiting release mechanism is removed, air in an air chamber of the impact cylinder can drive the piston assembly to make accelerated motion downwards; and when the piston collides a shock pad arranged on an anvil, a required impact acceleration and a pulse duration are generated. The pneumatic type high acceleration vertical impact table is compact in structure, easy to operate, capable of generating large impact energy and realizing different impact accelerations and pulse durations by adjusting an inflation pressure and the shock pad. The pneumatic type high acceleration vertical impact table is particularly suitable for a sample of which the mass is less than 0.5kg, and a acceleration of 500g-5000g and a half-sine impact wave shape with pulse duration of 10ms-3ms can be generated.

Description

technical field [0001] The invention relates to the impact test of the mechanical environment test technology, in particular to a pneumatic high-acceleration vertical impact table. Background technique [0002] The impact testing machine is mainly used for the mechanical environment test of the product, which can simulate the actual impact pulse and impact energy, and assess the expected impact environment of the product during use, loading and unloading and transportation, so as to determine the adaptability of the product to various impact environments . [0003] The vertical impact testing machine at home and abroad mainly adopts the method of free fall. The principle is that the test product is installed on a platform, and the platform is raised to a certain height in a certain way, and then the platform is released, so that the platform and the product fall freely to the anvil. On the anvil, an impact pad is installed to generate the required impact wave. According to...
