Dynamic Shaker Random Vibration Testing of Shipping Containers ASTM
D4728
ASTM_4728.pdf
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.
