Introduction:

Vibration testing system simulate the vibration environment under the
laboratory condition, and test the impact strength as well as reliability of
various vibration test applications. In the laboratory, with the aid of
vibration testing system, simulations of reproduction of sinusoidal, random,
resonant search and dwell, classical shock and road models, etc. can be
achieved. It is essential for product quality assurance, new product research
and development.



A complete set of vibration testing system is composed of shaker, power
amplifier and vibration measuring control system, in accordance with the
relevant national and international standards (such as: MIL-STD, DIN, ISO,
ASTM, IEC, ISTA, GB, GJB, JIS, BS, etc.) to provide technical support for
establishing product quality inspection.

Horizontal oil film slip table


The horizontal slip table is designed to have high tilting moment and lateral
restriction. This design concept is combined with standard horizontal slip
table to enable high dynamic moment limit and keep guide oil film damping
feature. The horizontal slip table is composed of a slipper, a connector, a
natural granite slab, horizontal slip table base and an independent oil source.
