| 摘 要： | 在中等变形梁的基础上引入增广转换矩阵,为解决桨叶动能项推导编程计算较为复杂的问题,建立了一种新的递推计算方法。该方法在原有的转换矩阵基础上进行了增广,建立了相邻运动坐标系间动能项引起的质量、阻尼、刚度和广义力递推计算方法。以法国SA349/2小羚羊直升机的试飞测试数据为依据,验证了方法的有效性。

| Abstract: | Based on moderate deflection beam model the extended transformation matrixes were introduced in this paper.To solve the complexity arising in the process of dealing with kinetic energy terms,a new recursive method was introduced.The original transformation matrixes were extended and the recursive computation methods of mass,damp,stiffness and generalized force matrixes induced by kinetic energy between two adjacent coordinate frames according to the two motions were derived.Results are corrected with SA 349/2 Aerospatiale Gazelle flight test data. |
