【摘要】：截面結(jié)構(gòu)強(qiáng)度分析校核方法是風(fēng)力機(jī)葉片設(shè)計(jì)優(yōu)化的關(guān)鍵問(wèn)題。針對(duì)現(xiàn)有的葉片工程力學(xué)計(jì)算方法精度不高、有限元分析方法計(jì)算開銷較大的問(wèn)題,在研究風(fēng)力機(jī)復(fù)合材料葉片結(jié)構(gòu)設(shè)計(jì)模型的基礎(chǔ)上,基于復(fù)合材料力學(xué)理論,推導(dǎo)出計(jì)算葉片截面周向各處拉伸和剪切應(yīng)變的計(jì)算公式;在葉片生命周期內(nèi)的極限載荷下,對(duì)某1.5 MW葉片進(jìn)行了結(jié)構(gòu)強(qiáng)度計(jì)算和分析,通過(guò)與該葉片在當(dāng)量極限載荷下的測(cè)試結(jié)果對(duì)比,驗(yàn)證了所述方法的有效性。
[Abstract]:The strength analysis and checking method of cross-section structure is the key problem in the design optimization of wind turbine blade, aiming at the problem that the accuracy of the existing blade engineering mechanics calculation method is not high, and the calculation cost of finite element analysis method is high. On the basis of studying the structural design model of composite blade of wind turbine, and based on the theory of composite material mechanics, the formulas for calculating the tensile and shear strain of blade section in circumferential direction are derived. The structural strength of a 1.5 MW blade is calculated and analyzed. The effectiveness of the proposed method is verified by comparing with the test results of the blade under the equivalent limit load.
