KRD15 Pneumatic Horizontal Shock Response Spectrum Test System

Name: KRD15 Pneumatic Horizontal Shock Response Spectrum Test System
Brand: CME Technology Co., Ltd.

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 srs test 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.

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.
