风电叶片用Balsa木原料平压性能检测分析数据

Balsa木是目前风电叶片最主要的芯材，通过模拟高压环境，根据压缩强度和模量来对产品进行分级，试验结果可为风力发电机设计商提供数据模拟支撑。平压性能检测能够直接反映其在受到压力作用时的稳定性，确保在后续应用中能够承受预期的压力，也可以筛选出抗压性能优良的Balsa木原料，从而提高整体产品的质量和稳定性，也避免了因使用劣质材料而导致的资源浪费和环境污染问题。在对产品稳定性和安全性要求极高的领域，其平压性能直接关系到后续风机的使用寿命和安全性，该检测可以有效降低风机在使用过程中出现意外的风险。测量试样任意三处的长度、厚度和宽度，使用万能试验机对目标试样进行测试，平压性能通过公式计算：平压强度计算公式σ=P/S,其中（σ--平压强度Mpa；P--载荷N；S--试样横截面积），若压缩强度数据小于5.7Mpa，则评为D级；大于等于5.7且小于10MPa的，则为C级；大于等于10且小于15MPa的，则为B级；大于等于15MPa的，则为A级；平压模量计算公式Ec=(h-tf2-tf1)×∆P)/(S×∆h),其中（Ec--平压模量Mpa；h--试样厚度mm；∆P--载荷/变形曲线上直线段的载荷增量N；∆h--对应∆P的剪切变形增量值mm；tf2，tf1--下面板、上面板厚度，纯芯子的时，记作0计算，单位mm），若压缩模量数据小于1630Mpa，则评为D级；大于等于1630且小于3500MPa的，则为C级；大于等于3500且小于4500MPa的，则为B级；大于等于4500MPa的，则为A级。Balsa wood is currently the primary core material for wind turbine blades. This work grades products based on their compressive strength and modulus by simulating high-pressure environments, and the test results can provide data simulation support for wind turbine designers. The flat compressive performance test can directly reflect the stability of the material under applied pressure, ensuring that it can withstand the expected pressure in subsequent applications. It also enables screening of balsa wood raw materials with excellent compressive performance, thereby improving the overall quality and stability of the product, and avoiding resource waste and environmental pollution caused by the use of inferior materials. In fields with extremely high requirements for product stability and safety, the flat compressive performance is directly related to the service life and safety of subsequent wind turbines, and this test can effectively reduce the risk of accidents during wind turbine operation. First, measure the length, thickness and width at any three positions of the test specimen. Then, a universal testing machine is used to test the target specimen. The flat compressive performance is calculated via the following formulas: 1. Flat compressive strength: σ = P/S, where σ stands for flat compressive strength (unit: MPa), P is the applied load (unit: N), and S is the cross-sectional area of the test specimen. The grading criteria based on compressive strength are: - Grade D: Compressive strength < 5.7 MPa - Grade C: 5.7 MPa ≤ Compressive strength < 10 MPa - Grade B: 10 MPa ≤ Compressive strength < 15 MPa - Grade A: Compressive strength ≥ 15 MPa 2. Flat compressive modulus: Ec = (h - tf1 - tf2) × ΔP / (S × Δh), where Ec stands for flat compressive modulus (unit: MPa), h is the thickness of the test specimen (unit: mm), ΔP is the load increment in the linear segment of the load-deformation curve (unit: N), Δh is the shear deformation increment corresponding to ΔP (unit: mm), tf1 and tf2 are the thicknesses of the top and bottom panels respectively. For a pure core sample, tf1 and tf2 are taken as 0 (unit: mm). The grading criteria based on compressive modulus are: - Grade D: Compressive modulus < 1630 MPa - Grade C: 1630 MPa ≤ Compressive modulus < 3500 MPa - Grade B: 3500 MPa ≤ Compressive modulus < 4500 MPa - Grade A: Compressive modulus ≥ 4500 MPa
