剪切中心 meaning in English

shear center
shearing center

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的线性二维有限元分析模型为基础考虑了复合材料桨叶的结构和变形特点，计入了剖面翘曲的影响，在此基础上编制了具有八节点等参元复合材料桨叶剖面刚度计算的有限元程序，分析计算了复合材料梁的剖面刚度、弯曲中心、剪切中心；并利用半解析法进行剖面刚度、剪切中心、弯曲中心的参数灵敏度分析。
