Vibration Tester. 

Vibration Tester For Transport Packages - The effect of vibrations experienced during transport on packaged materials is normally determined by subjected them to a simulated vibration test. In this test, the package under test is placed over a vibrating table capable of moving about a vertical axis by a fixed amplitude at a fixed frequency. The effect of a specified number or period of vibrations on the packed materials is observed to evaluate the resistance provided by packaging to such vibrations. The Globe Vibration Tester for transport packages consists of horizontal table mounted above an oscillating block and rigidly connected to it. This table is given oscillatory movement of a fixed amplitude by the movement of the block, which is in turn held over two hardened and ground carbon steel rods and is given an oscillatory movement with the help of an electric motor coupled to a V-belt and speed reduction pulley arrangement. The block has two gunmetal bushes to give it a long working life. The rotary movement of the pulley is converted into linear movement of the block with the help of an eccentric pin and a linkage mechanism. The eccentric pin is fixed to a disc mounted on the shaft on which the pulley is mounted. In the fixed frequency model of the tester, the frequency of vibrations is set at 4 Hz. In the variable frequency model it can be set at any desired value in the range of 1 to 8 Hz with the help of a variable frequency inverter drive supplied with the equipment. A six digit electronic counter with non-contact infrared sensor is provided to record the total number of oscillations undergone by the components under test. The counter has a memory backup to retain the count of number of oscillations undergone in case of accidental switching off of power supply to the equipment. A key-operated reset switch is provided to reset the count to zero at the end of test duration. The package under test is placed on the vibration table. It is prevented from dropping down by a low level guard along the periphery of the table. The table is square in shape so that the package can be rotated through 90° after every 25% of total number of specified oscillations. civil lab equipments manufacturers
