Application Note: Laser Vibrometry And The Automotive Industry

Laser vibrometry is firmly established as the automotive industry's gold standard for non-contact vibration measurement. Its advantages are many including zero-mass loading, high precision and sensitivity, fast set-up, ease of operation and long standoff distance. By combining a single-point laser vibrometer with 2-D fast-scan mirrors, vibrations can be characterized over an entire surface. This exciting test and measurement procedure is revolutionizing design development and experimental modal analysis in the automotive industry. Polytec's comprehensive line of products and services provide an optimal solution for almost every automotive vibration measurement application.

Automotive Applications:

• Experimental modal analysis
  
• Measurements on engine valve train assemblies
  
• Brake development
  
• Acoustic optimization of vehicle components
  
• Axle vibrations, bending and torsional modes
  
• Quality testing and industrial process control
