Foreword

GB/T 22906 "paper core measurement" is divided into nine sections. --- Part 1. sample taken; --- Part 2. temperature and humidity of the treated samples; --- Part 3. Determination of moisture content (oven drying method); --- Part 4. Determination of dimensions; --- Part 5. Determination of characteristics of concentric rotation; --- Part 6. Determination of flexural strength (three-point method); --- Part 7. Determination of modulus of elasticity (three-point method); --- Part 8. Determination of natural frequency and the elastic modulus (experimental modal analysis); --- Part 9. Determination of flat crush strength. This section GB/T Part of 822,906. The partial modification of the use of ISO 11093-8.1997 "Paper and board Determination - Part 8. Determination by experimental modal analysis of solid It has a frequency and modulus of elasticity. " This part of ISO 11093-8.1997 compared to the main differences are as follows. --- International Standard ISO document standard will be referenced in normative references converted to its corresponding national standard, 22906.2 paper core measurement GB/T Part 2. temperature and humidity of the treated samples (ISO 11093-2.1994, MOD). This part is proposed by the China National Light Industry Council. This part of the paper by the National Standardization Technical Committee (SAC/TC141) centralized. This section drafted by. China Pulp and Paper Research Institute, China Paper Association Professional Committee of Standardization. The main drafters of this section. Cui Liguo. Determination Zhixin Part 8. natural frequency and Determination of the elastic modulus (experimental modal analysis)

1 Scope

This section GB/T 22906 specifies the transverse vibration test model using the free ends of the paper core to determine the natural frequencies and elastic modulus Test methods for. This section applies to an inner diameter of 50mm ~ 350mm, the minimum wall thickness of not less than 0.02 times the inside diameter or 2.0mm, minimum length 8 times the inner diameter of the core.

Principle 4 In the test model analysis, the paper core sample is considered to be "bending beam" application "Timoshenko curved beam theory," Determination of isotropic Lateral vibration of the sample. In this theory, considering the shear deformation generated when the rotational inertia and lateral vibration. During the test, Sample free to vibrate in the direction of its cross-section. Modulus of elasticity of the provisions of Chapter 8 shall be calculated.

5 Instruments

5.1 specimen support means The basic principle is to test the model in transverse vibration free ends, the determination of the natural frequency of the sample. To ensure that the sample in the cross-plane direction ......
