Abstract
PURPOSE: To perform shock simulation test easily with simple constitution, by providing the unit taking the signal value integrating twice the burdened load as the set signal of jack and colliding the electro-hydraulic servo type jack to the measured body.
CONSTITUTION: The speed Vo immediately before the jack plate 7 collides with the inspected object 1 is set to the speed setter 14, and the hydraulic source 18 drives the cylinder of the jack 6 via the servo valve 17. Although the speed of the jack plate 7 is changed by receiving the reaction force at collision immediately after the collision, the state is detected at the piston displacement detector 9 via the jack plate 7, and the displacement signal is amplified at the piston displacement amplifier 10 and fed to the feedback point 16. On the other hand, the state of the weight change immediately after the collision is detected at the load detector 8, and the signal in two integrations is fed to the feedback point 16 with the integrators 12, 13. The entire process of destruction can be simulated with this servo control.
