KRD11 PNEUMATIC VERTICAL SHOCK TEST MACHINE

KRD11 is a fully automatic pneumatic lifting vertical shock test machine. It is
vertical shock test equipment with a novel design, high degree of automation,
simple operation, and convenient maintenance. It is used to measure and
determine the impact resistance of products or packaging and assess the
functional reliability and structural integrity of the test product in a shock
environment. KRD11 series pneumatic shock test system meets the requirements of
both shock and bumps test, shock testing waveform including conventional half-
sine wave, post-peak sawtooth wave, trapezoid wave, to realize the shock wave
and shock energy that the product is subjected to in the actual environment,
thereby improving the system or optimizing the structure of the product. This
equipment meets standards of IEC68-2-27, MIL-STD-202, MIL-STD-750, MIL-STD-810,
MIL-STD-883, etc.

FEATURES OF KRD11 VERTICAL pneumatic shock test machine

Pneumatic drive, simple structure and high reliability, without hydraulic leak
risk.

Pollution free, without hydraulic leak risk and keep the environment clean.

Pneumatic drive greatly improves the shock test efficiency, maximum shock rate
up to 120 times / min.

Impact testing for small pulse lower to 0.3ms.

Shock testing machine with high acceleration is up to 3000g.

It can easily realize large shock pulse width and small overload test.

With a fast shock rate comparing to motor or hydraulic driven collision-bump
table, it has higher reliability and better collision-bump waveform.

The speed and rate of shock can be easily controlled by adjusting the gas
pressure.

IPS-2000 shock control and measurement system can perform manual shock,
continuous shock (bump test), single shock, and interval shock.

Built-in brake mechanism ensures the safety of operation in any situation.

TABLE OF KRD11 PNEUMATIC VERTICAL SHOCK TEST MACHINE
The test sample is installed on the worktable, which is guided by two high-
precision sliding guides and can move up and down. The two cylinders are
connected to the worktable by sliding guides. When the cylinders are inflated,
the piston rod rises to drive the worktable to lift. The workbench is lifted.
When it is raised to the set height, the cylinder quickly deflates, and the
bottom surface of the worktable hits the waveform generator to complete a shock
process.

By adjusting the rising height of the worktable, different initial shock speeds
can be obtained, and thus different shock overload values can be obtained;
while changing the stiffness of the waveform generator, different pulse width
values can be obtained. The structure schematic diagram is shown in following
figure:

DUAL MASS SHOCK AMPLIFIER OF KRD11 PNEUMATIC VERTICAL SHOCK TEST MACHINE
The shock amplifier is a device that uses the rebound energy of the ordinary
shock table to realize the opposite impact between the servo table and the seat
on the amplifier so that the impact acceleration is multiplied.

WAVEFORM GENERATORS FOR KRD11 PNEUMATIC VERTICAL SHOCK TEST MACHINE
KRD11 pneumatic 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:
