Hydraulic Vertical Vibration Table

WESTEST operates a Vertical Vibration Table capable of developing vertical motion / acceleration to produce a number of test excitation methods. It is used in the lab to evaluate a test specimen's response to vibration excitation in the vertical axis. This hydraulically driven vibration table is capable of producing vibrations up to 100 Hz, making it ideally suited for evaluating components and assemblies used in or on ground based vehicles and machines. WESTEST regularly uses this vibration table to perform sine sweeps and durability tests.

Hydraulic Vertical Vibration Table Specifications:

  • Frequency range: 0 - 100 Hz
  • Table size: 72" X 72" (Extension brackets can be installed for larger test samples)
  • Maximum payload weight: 6,000 lb
  • Displacement: ±3 inches
  • Acceleration: Dependent on test sample weight and frequency
  • Program / command options include sinusoidal, random, and actual field vibration simulation with RPC software

The Vertical Vibration Table Provides:

  • A versatile mounting surface for attaching diverse test samples
