A controller (more properly a Vibration Control System or VCS) is required to force the moving shaker table to impose the desired acceleration profile to the DUT. No foundation needed, excellent isolation of vibration and lower noise during operation.

Get Price. Shaker tables can be related to any of the following product options:The 9110D and 9210D calculate and display test sensor sensitivity on the readout screen in real time. Shakers are used to subject a Device Under Test (DUT) to random, swept-sine and transient shocks.

0000992555 00000 n They offer air and water-cooled shakers with maximum force ratings from 20 N (4.5 lb) to 400 kN (88,000 lb) with strokes ranging from ± 4 mm (± 0.16 in) to ±100 mm (±3.9 in). 0000022402 00000 n 0000016990 00000 n These shaker tables for vibration testing are characterized by: Constant stroke; Low accelerations; Very low frequencies.

The response motion of the shaker’s table is monitored by the accelerometer which returns the CONTROL signal to the VCS. These include demonstration of compliance with standards, new design qualification, stress screening, fatigue life evaluation, shock and earthquake survivability demonstration and various product pre-shipment audit and burn-in tests. 0000015186 00000 n They have more than 20 years of experience studying packaging engineering and vibration analysis.Within the range of vertical vibration systems, Safe Load offers a wide range of options: frequencies that can reach up to 500Hz, test loads of more than 1500kg.One of the features is the possibility of two types of maximum stroke, one of 75mm to simulates all the standard procedures ISTA, ISO, ASTM… and another with a stroke of 200mm.This machine with longer stroke offers the possibility of simulating any type of tests, the standard procedures, but also, thanks to the controller of Real Vibrations, can simulate any PSD of a real transport route registered by a (Safe Load TT), or any other vibration recorder of the market.Real vibrations controllers have 3 kind of control interfaces depending on the level of the final user: simple mode, advanced mode or scientific mode, designed for research and simulation centers.The technology patented by Safe Load allows us the possibility of performing angular P&R vibrations.The standard vibration shakers of Safe Load TT offer rotations of ±5⁰, anyway, as in all their machines, Safe Load TT offers the possibility of customizing these rotation limits under customer specifications.

Are used mostly at the laboratory level as mechanical agitators. 0000002298 00000 n 0001029776 00000 n

0000010087 00000 n In addition, this shaker/amplifier must be controlled by a vibration controller with sufficient dynamic range to assure robust and repeatable control of every test with sufficient measurement channels to provide full protection and understanding of your tested device. Vibration testing on electrodynamic or hydraulic vertical shakers (and on shaker-driven horizontal slip tables) is done for a broad range of reasons. The VCS is programmed with the desired PROFILE of the test (either an acceleration-versus-frequency spectrum or an acceleration-versus-time history).

Vibration response and fatigue tests.These shaker tables for vibration testing are characterized by: Are used mostly at the laboratory level as mechanical agitators. 0000439290 00000 n
