Built -in impact hamma 8206 type series of preamplifiers and acceleration corrections
Hottinger Brüel & Kjær
About This Product
In contrast to the use of a dynamic power type, the impact hammer offers a very portable solution for excitation without adding additional mass load to the test object.
■ Use
・ Measurement of impact input from small to medium structures
・ Measurement of frequency response function due to impact collapse
・ Structural test system such as experimental mode analysis and response prediction test
■ Characteristics
・ 4 types by sensitivity of 1-22 MV/n
・ Handles based on human engineering design
・ Do not change the dynamic characteristics of the test object
・ 3 types of advanced chips
・ Built -in acceleration correction
■ Explanation
This impact hammer series is designed for small to medium -sized structures, that is, engine blocks, body frames, car components, etc. Use acceleration pickup (or laser speedometer, etc.) to measure the response to the vibration. You can use a multi -channel FFT analyzer like a Pulse ™ system to find a frequency response function and mode shape for the test object. Unlike a dynamic power transferor, impact hamma does not add mass to the test object and can be carried.
■ Characteristics
The 8206 impact hammer series has a built -in preamplifier, and its output sensitivity is represented by the output voltage per unit force (MV/N or MV/LBF). In addition, hammer has a built -in acceleration correction and removes unnecessary noise from the output signal of the hammer. As a result, you can get a beautiful and smooth allocation signal in both the amplitude and phase. The hammer is provided along with three types of exchanged impact chips, aluminum, plastic, and rubber. Depending on the type of chip, the impulse waveform (amplitude and duration) and the vibration frequency range are different.
You can increase the weight of the head part using the 40 Gram head extensioner. The handle is designed based on an ergonomic to make it easier to control the impact, and the frequency of "double hits" is reduced.
■ Calibration
The hammer is provided according to the individual proofreading sensitivity value.
