Title:
SHOCK TESTING DEVICE
Document Type and Number:
Japanese Patent JP2010008405
Kind Code:
A
Abstract:
To provide a testing device that exerts impact acceleration on a test piece, using a simple constitution.
The test piece TP is fixed to a low end of a hydraulic cylinder 10. An upper oil chamber 15 in the hydraulic cylinder 10 is connected to a tank 7 via a flow rate regulating valve 6, and a lower oil chamber 16 is connected to an accumulator 3. With the flow-rate regulating valve 6 in a closed state, pressure oil from a hydraulic pump 4 is accumulated in the accumulator 3, in advance. When the flow-rate regulating valve 6 is opened in this state, a piston 13 rapidly rises due to oil pressure from the accumulator 3, and impact acceleration acts on the test piece TP.
