Ударно-вібраційний випробувальний стенд

Abstract

Impact-vibration testing testbench has basis, movable in direction of impact table, pneumatic-hydraulic accelerator connected to it with over-piston cavity connected to gas power source, and under-piston cavity is connected through discharge channels and controlled throttle opening to discharge cavity. Additionally there is included device for control of impact pulse arranged as tubular gate the ends of which through channels are connected to electro-hydraulic amplifier, this through electromagnetic system of connected to electronic amplifier and generator of electric signal. Under-piston cavity is connected through back valve and distributor with source of hydraulic energy.
