HAMMER IMPACT TEST DEVICE AND HAMMER IMPACT TEST METHOD

摘要

PROBLEM TO BE SOLVED: To allow a simple configuration to prevent a first oscillation generated by giving an electromagnetic impact from propagating to a can body.SOLUTION: A hammer impact test device 1 comprising: a hammer impact head 10 that gives a can body C an electromagnetic impact, receives a hammer impact sound to be emitted from a hammer impact oscillation part of the can body C, converts the hammer impact sound to a hammer impact signal, and outputs the hammer impact signal; and a computation device 20 that analyzes the hammer impact signal and discriminates a can inner pressure of the can body C, the hammer impact test device comprises first oscillation suppression means 40 that prevents a first oscillation generating in a can lid C3 of the can body C when the electromagnetic impact is given.SELECTED DRAWING: Figure 1
