KRD17 BIDIRECTIONAL VERTICAL SHOCK TEST SYSTEM

KRD17 series is a new designed fully automatic pneumatic lifting bidirectional
shock test system with high degree of automation, simple operation and
convenient maintenance. It is a bidirectional vertical shock test system
developed for measuring and determining the impact resistance of large
specimens without turning over them, and assesses the functional reliability
and structural integrity of the specimens. It is especially used in the field
of battery testing, can perform various conventional classic vertical upward
and downward shock tests in one test table to realize the shock wave and impact
energy suffered by the product in the actual environment. This equipment meets
standards of IEC68-2-27, MIL-STD-202, MIL-STD-750, MIL-STD-810, MIL-STD-883,
UN38.3 and other battery testing standards.

TABLE OF KRD17 BIDIRECTIONAL VERTICAL SHOCK TEST SYSTEM
This bidirectional shock test table is composed of a circulating air storage
cylinder, a pneumatic self-locking control mechanism up and down each, a
forward impact plate, a reverse impact plate, a locking mechanism, a base, and
other parts.

The circulating accumulator is used as the shock power cylinder. The pneumatic
brake device locks the table at the set position. The circulating accumulator
is inflated. After the air pressure reaches the set value, the locking device
is controlled to release, and the circulating storage cylinder drives the table
to accelerate upward and downward movement, and impacts the waveform generator
on the impact plate to produce the required shock waveform.
Come and buy testing equipment.

DUAL MASS SHOCK AMPLIFIER OF KRD17 BIDIRECTIONAL VERTICAL SHOCK TEST SYSTEM
The shock amplifier is a device that uses the rebound energy of the ordinary
impact shock table to realize the opposite impact between the servo table and
the seat on the amplifier so that the impact acceleration is multiplied.

WAVE GENERATORS OF KRD17 BIDIRECTIONAL VERTICAL SHOCK TEST SYSTEM
KRD17 series bidirectional shock test system is equipped with a half-sine wave
generator. The half-sine wave generator is mainly made of engineering rubber
(considering the stiffness and cohesive force of rubber) and felt pads of
various thicknesses. Different thicknesses are connected in series to form
multiple stiffnesses to achieve different shock pulse widths. Optional for
post-peak sawtooth wave generator which is lead cone; trapezoidal wave
generator air source is high-pressure nitrogen, the pressure range is 1-10MPa,
and the overload value can be adjusted between 10-100g, as shown in the
following figure:
