KRD12 series shock tester is a pneumatic cylinder driving horizontal shock/bump testing machine with the advantages of ingenious design, high technical performance, high safety and reliability, and easy operation. The pneumatic shock test machine is suitable for evaluating the functional reliability and structural integrity of various products under horizontal shock or bump environments, so as to improve or optimize the structural design or product structure.

It is shocking test equipment is mainly aimed at the specimen that cannot be realized by the vertical shock table or the fixture must be installed horizontally. KRD12 series pneumatic horizontal shock test machine is the multi-functional design of the test machine combined with the shock test and the bump test, is the mainstream product of current classic horizontal shock test requirements. This horizontal shock testing machine complies with IEC68-2-27, MIL-STD-202, MIL-STD-750, MIL-STD-810, MIL-STD-883, and other standards.

FEATURES OF KRD12 PNEUMATIC HORIZONTAL SHOCK TEST MACHINE 
Adopts full pneumatic drive: short accelerating stroke, large driving force, low cost, and no pollution; large pulse width and small overload test can be easily realized.
High-performance forged super-duralumin table:forged super-duralumin table has high strength, hardness, and high first-order resonance frequency.
Adopts sliding guide rails:the working table runs smoothly during the shock, and the clutter is greatly reduced.
Integrated control & measurement system:control and measurement of one machine management, convenient operation.
Easy operation:all operations are based on Windows and completed on the computer, which is easy to operate and highly automated.
IPS-2000 shock control & measuring instrumentcan accurately complete the shock test; the software integrates shock control and data acquisition;
Built-in double-brake system:the quick-release valve and the photoelectric switch are used together to simply solve the problem of the secondary rebound; safe and reliable.
Multiple functions:can perform shock or bump test, can be designed as a bidirectional shock according to user needs, saving test time more effectively.
High safety & reliability:safety gratings are designed in the working area of the response table, which effectively prevents misoperation and protects the safety of test personnel.

TABLE OF KRD12 PNEUMATIC HORIZONTAL SHOCK TEST MACHINE
KRD12 pneumatic horizontal shock tester is composed of a test machine body, shock control measurement controller, pneumatic system, waveform generator, and other parts.

The shock table is a rigid structure, and there are mounting holes on the table, which are mainly used to support the test fixture. By changing the installation method or direction of the test product, tests in different directions can be carried out.

The pneumatic horizontal shock testing table consists of a working table, shock push plate, control cylinder, grating sensor, pneumatic self-locking mechanism, pneumatic return device, etc. The schematic structure is shown in the figure.

Waveform Generators of KRD12 Pneumatic Horizontal Shock Test Machine

The pneumatic horizontal shock and vibration test system is equipped with a fixed half-sine wave generator. The half-sine wave generator is mainly made of engineering rubber and industrial felt (considering the stiffness and polymerization force of rubber). A waveform generator is generally designed with several different thicknesses. Different thicknesses are connected in series to form a variety of stiffness 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:
