vImpact Hammer

The new vImpact Automatic Modal Hammer provides precise and repeatable impact excitation for experimental modal analysis. Its precise operation eliminates "double hits" and takes the variability of human operation out of testing.

With excitation up to 40 kHz in frequency, the vImpact hammer is highly suitable for laser vibrometer as well as acoustic experiments. The system consists of three components:

• Hammer Head
• Control Unit
• Interconnect Cable

 

 

 

 

The vImpact hammer can be triggered through several methods:

• Manually by pushing the trigger button
• Automatically with a variable internal timer (from 4 hits per second to 1 hit per minute)
• Automatically from an external trigger source

 

 

 

Key Specifications:

• Frequency Range: 0 - 40 kHz
• Sensitivity: 22.5 mV/N
• Measurement Range: 222 N peak
