The design of structure and dynamics of a rotor blade is based on its section characteristic of composite blade 因此,一個精確的剖面特性的分析計算方法對旋翼槳葉設(shè)計是十分重要的。
The vibration modal parameters such as natural frequencies , damping ratios are analyzed . the study work provides powerful technique support for the design and manufacture of composite blade 研究表明,利用理論的方法預(yù)測三維機(jī)織復(fù)合材料的彈性模量和動態(tài)力學(xué)性能是可行的,為復(fù)合材料葉片的設(shè)計和制造奠定了基礎(chǔ)。
Now , it is important to develop the composite blade researching , two measures including analysis methodology and finite methodology are provided . in this text , the finite rotation composite beam theory developed by hodges and his co - workers , during the late 1980 ' s , is adopted in order to research rotor of helicopter . a liner and two - dimension finite analytic measure is used to calculate the section characteristic and strain of the blade ; a semianalysis methodology is used to calculate the sensitive degree of section characteristic 以giavotto的線性二維有限元分析模型為基礎(chǔ)考慮了復(fù)合材料槳葉的結(jié)構(gòu)和變形特點,計入了剖面翹曲的影響,在此基礎(chǔ)上編制了具有八節(jié)點等參元復(fù)合材料槳葉剖面剛度計算的有限元程序,分析計算了復(fù)合材料梁的剖面剛度、彎曲中心、剪切中心;并利用半解析法進(jìn)行剖面剛度、剪切中心、彎曲中心的參數(shù)靈敏度分析。
