0000001899 00000 n Perform Vibration Testing for reliability Our thin shake tables and light, portable bench top shakers are typically part of the vibration test equipment used in educational, research and laboratory environments.
This precision hardware is supported by a complete range of testing software to accomplish virtually any type of test your enterprise requires.A complete testing system consists of a VCS, a shaker, a power amplifier to drive the shaker and an accelerometer mounted on the shaker’s vibrating table.
Sophisticated real-time algorithms and circuitry within the VCS function to refine the DRIVE signal with time, forcing the CONTROL response to match the desired PROFILE. They also have built-in ICP® input for common piezoelectric accelerometers. Universal procedures have been studied to achieve that: ISTA, ASTM, ISO, etc., procedures.To predict the damages in both cases (final products or packaging) are the vibration testing tables. The shaker table is designed to be the test platform where the testing object (electronic device) is attached on the table.

0000011060 00000 n This king of vibration machine is also used in some testing standards: ISTA, ASTM, TAPPI, ISO, MIL-STD, UN, DOT. 0000440561 00000 n 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. Get Price. Vibration testing on electrodynamic or hydraulic vertical shakers (and on shaker-driven horizontal slip tables) is done for a broad range of reasons. 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. Vibration response and fatigue tests.These shaker tables for vibration testing are characterized by: Are used mostly at the laboratory level as mechanical agitators. 0000019247 00000 n

Shaker Tables for Vibration Testing and Calibration In the world of vibration testing the words “shaker table” or vibration table can have many different meanings Shaker tables are used to perform various types of testing from general vibration testing of components to vibration testing of structures or even calibration of dynamic In the world of vibration testing, the words “shaker table” or "vibration table" can have many different meanings. 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). The VCS also performs a myriad of related functions including pre-test feasibility analysis (can this shaker/amplifier perform this test on this DUT and its mounting fixtures? As a surface platform, the table should behave as a rigid body to transmit vibration from the shaker to … 0000010689 00000 n
