GB/T 22906.8-2008 "Testing of cores - Part 8: Determination of natural frequency and modulus of elasticity by experimental modal analysis" specifies a method for determining the natural frequency and modulus of elasticity of paper cores using a free-free transverse vibration test model. This standard is applicable to paper cores. The natural frequency is obtained by exciting transverse vibration, and the modulus of elasticity is calculated based on dimensions and mass. The standard clarifies the test apparatus, vibration parameters, and data processing, reflecting the structural mechanical properties of paper cores.
