Elevating Low-Frequency Performance: Crafting Vibration Test Table Foundations

50kn 1

Introduction: Welcome back to the second part of our series on vibration test table foundations. In this segment, we explore the intricate requirements and considerations involved in crafting foundations that enhance the low-frequency performance of vibration tables.

I. Addressing Low-Frequency Challenges: When vibration shakers operate in the lower frequency spectrum, challenges arise due to resonance between the table body and isolating air springs. To overcome these challenges, the fundamental solution involves constructing foundations with substantial inertial mass. By strategically locking isolating air springs, these foundations become pivotal in absorbing reactive forces and providing stability during low-frequency operations.

II. Comprehensive Foundation Requirements: Crafting foundations for optimal low-frequency performance requires meticulous attention to specific requirements:

  1. The inertial mass of the foundation base should maintain an 8:1 ratio to the maximum thrust of the vibration table (in kg).
  2. Vibration tables operating below 3-5Hz must adhere to strict constraints on maximum acceleration relative to peak acceleration and vibration displacement.
  3. A firm and integral connection between the vibration table’s body and the high-mass foundation is paramount.

Conclusion: By understanding and adhering to these comprehensive foundation requirements, engineers can ensure the stability and optimal performance of vibration test system across various frequency spectrums. These foundations become the cornerstone for confident deployment in diverse testing scenarios without compromising precision or causing disruptive effects on surrounding structures.
