KRD15 PNEUMATIC HORIZONTAL SHOCK RESPONSE SPECTRUM TEST SYSTEM

KRD15 pneumatic horizontal shock response spectrum tester is the special
equipment for spectrum specification shock test, so it can also be called
spectrum specification shock machine. The advantages of this equipment are
convenient energy adjustment, simple and compact structure, easy operation, and
a good repeatability of test results. It is the state-of-the-art shock response
spectrum tester, using compressed gas energy to provide impact energy, and the
shock hammer is pushed to impact the resonance plate to produce high-energy
impact. It can meet the requirements of various spectrum specifications
established by the current aerospace system, mainly applied in the industries
of aerospace, aviation, and ships.

FEATURES OF KRD15 PNEUMATIC HORIZONTAL SHOCK RESPONSE SPECTRUM TESTING SYSTEM

Adopts pneumatic energy storage to drive the shock hammer, with a large driving
force, reliable structure, and fast response speed

Adjust the driving shock energy by adjusting the air pressure, which is easy to
operate and high in efficiency

Two-level safety switch is designed to fully protect the safety of operators

Designed with a special base, is mainly to raise the installation position of
the response plate, which is convenient for users to install the specimen and
adjust the gasket operation

All operations are completed on the integrated measurement and control
software, which is easy to use and has a high degree of automation

TABLE OF KRD15 PNEUMATIC HORIZONTAL SHOCK RESPONSE SPECTRUM TEST SYSTEM
The main structure of the shock response spectrum tester mainly includes a test
machine table, a shock response spectrum control measurement analysis system,
etc.

KRD15 pneumatic horizontal shock response spectrum tester mechanical system
consists of a shock table, a response plate, a pneumatic self-locking
mechanism, a pneumatic return device, etc.

The specimen is installed on the response plate of the horizontal shock
response spectrum tester. When the shock hammer shocks the response plate, the
specimen on the response plate produces the corresponding move after the shock
is applied. The acceleration sensor collects the acceleration on the response
plate and performs the response spectrum analysis.

ACTUAL PHYSICAL SYSTEM IS DIVIDED INTO MULTIPLE SINGLE DOF SYSTEM PHYSICAL
MODELS
An actual physical system can be decomposed into multiple different single-DOF
systems. For each single-degree-of-freedom system, analyze and calculate the
shock response spectrum, and finally synthesize it to get the shock response
spectrum of the entire system, as shown in Figure 1 below.
