PURPOSE:To attain a tester where the height of a vibration table plate is changed easily, by adjusting the quantity of air supplied to an air suspension to change the internal pressure of the air suspension. CONSTITUTION:An oscillatory table plate 1 where an object to be tested is placed and is oscillated is fixed onto a bellows 3 as the air suspension by fixing metallic tool 2. The bellows 3 is made of neoprene or the like, and a girdle ring 4 is fitted to a recessed part between two stages of expanding parts, and the lower end of the bellows 3 is fixed to a fixed plate 7 on a controller 6 by a fixing metallic tool 5. The girdle ring 4 prevents expansion of the bellows 3 to hold the oscillatory table plate 1 horizontal when the inside of the bellows 3 is pressurized. The controller 6 controls the quantity of air supply/discharge to an air vibrator 16 through an air pipe 8 and a valve by an air compressor 9 and is fixed to a base 10 by anchor bolts 11. |
