Basic Knowledge on Vibration Test System

[ To Calculate Force Output ]

For right System Model selection, the Force Output needed to carry out the required tests is to be calculated.The following formula is used for Force Output calculation:

F =(m₀ + M₁ + M₂)A

F : Force Output 〔N〕
A : Acceleration 〔m/s²〕
m₀ : Weight of Bare Table 〔kg〕
M₁ : Weight of Aux. Table and/or Fixture if any 〔kg〕
M₂ : Weight of Specimen 〔kg〕

When the test acceleration is unknown, the following formula is used. (Only for Sine tests)

A = 2πfV

A =(2πf)² D

f : Frequency 〔Hz〕
V : Velocity 〔m/s〕
D : Displacement 〔m0-p〕
A : Acceleration 〔m/s²〕
