The GK-2110, with its lightweight 4.8g hammer mass, allows for vibration excitation for noise analysis and countermeasures in small cases such as HDDs and thin-diameter pipes such as compressors.
The GK-4110G10, with its 1.1 kg hammer mass, enables vibration analysis of machine frames that affect machining accuracy, and vibration excitation for modal analysis of automobile white bodies.
With a built-in CCLD preamplifier, it can be directly connected to an analyzer. (The GK-4110G10 also supports TEDS.)
An impulse hammer is a vibrator widely used for structural analysis, crack inspection of components, and investigation of the causes of noise. By striking a structure or component with an impulse hammer to induce impulse vibration, capturing the response vibration with an NP series accelerometer or LV series Laser Doppler Vibrometer, and analyzing it with an FFT analyzer, the transfer function of the structure can be determined. This allows for resonance frequency analysis, modal analysis, crack inspection, and investigation of the causes of noise in structures and components.
The mass of the impulse hammer must be selected according to the object being vibrated. By using a small hammer for lightweight parts and a large hammer for heavy objects, the optimal vibration force can be obtained, enabling stable vibration. We have been selling the GK-3100 general-purpose impulse hammer until now, but to accommodate vibration of everything from small parts and structures to large machine tools and automobile white bodies, we have added two new models to our lineup: the ultra-compact GK-2110 with a mass of 4.8 g and the large GK-4110G10 with a mass of 1.1 kg.
