• Methodology
• Progress
• Next Steps

AREMA Vibration Guidelines

• Summary of Test Recommendations
• Section 11.5.1
• Sinusoidal Vibration Test
• Exploratory Sine Sweep (identify resonance)
• Mechanical Shock
• ex) Class A Sinusoidal
• Range / Levels
• 5 to 20 Hz 0.2 peak-peak
• 20 to 200 Hz 4.2 g-peak
• 12 Minute Sweeps (0.9 Octave/Minute)
• 4 Hours per Axis (20 cycles)

Review Project Scope

• Re-evaluate Current Specification.
• Current Spec - Accurately characterize
  environment?
• Possible over-test condition.
• Goal Develop scientific basis for vibration test
  specification.
• Ensures durable and reliable products.
• Avoids unnecessary design and test cost in new
  products.
• Field Study and Report
• Four railroad sites for data acquisition.
• Limit scope to Class A.
• ALSTOM investment, will share data and results
  with Committee.
• Full Presentation and Recommendation at C38,
  Spring 2004.

Methodology

• LMS Engineering Services contracted by ALSTOM
• Leader in the Vibration Industry
• State-of-the-art Equipment and Analysis Tools
• Experience in Specification Development
• Strong Project Management
• Statistical Analysis of Environment to identify
• Fatigue Damage Spectrum (FDS) (WEAR)
• Maximum Response Spectrum (MRS) (OVERSTESS)
