将带梁式柔性附件航天器的附件振动作为波动研究。将附件按物理特性的差异划分成单元,弹性波在每一个单元内传播,并在结点处反射、散射。通过考虑单元间的边界条件可以得到姿态动力学的解析模型,并由此可以获得外扰动和姿态角到附件弹性位移之间的传递特性。与传统的以混合坐标表示的模型相比,此模型能够获得更全面、更精确的姿态动力学特性。

Summer monsoon precipitation in 1998 is simulated with different soil temperature and solar short wave radiation parameterization schemes using the improved p σ nine level hybrid coordinate model.It is found that the improved soil temperature calculation method together with Lacis and Hansen short wave radiation parameterization has a good simulation for precipitation.Statistical test is also made,indicating that the soil temperature has great impact on the precipitation distribution.Compared with the observed field,this model simulated the precipitation better in some periods,while worse in other periods,such as for the strong precipitation process.

The traditional hybrid coordinate model of flexible m ultibody system is considered as a zero order approximate dynamic model due to its neglect of the high order coupling deformation kinematics. This a pproach fails to account for dynamic stiffening and may lead to erroneous re sults in some high speed cases. This paper presents a finite element model for a multibody system consisting of a rotating hub and a flexible beam with a tip m ass. The corresponding dynamics models of the viscous damping and air resistance are developed in a consistent manner. Based on the deformation theory and geome tric constraints, the longitudinal deformation due to the transverse deflection is t aken into account and the effect of dynamic stiffening is captured. This mod el is different from the model for dynamic stiffening problem in that the la rge overall motion of the reference frame of the beam is not prescribed and is a ffected by elastic deformation. A numerical example is given in the end, which i s more general than the well know n example for dynamic stiffening. This example illustrates not only the defic iency of the zero order approximate dynamic model more profoundly, but also the validity of the proposed model.

柔性多体系统动力学传统的混合坐标建模方法忽略了变形位移的高次耦合变形量 ,是一种零次近似方法 [1 ] ,其适用范围受到限制。本文以中心刚体、柔性梁及末端质量组成的刚柔耦合系统为对象 ,考虑了有粘性阻尼及风阻的情况。在柔性梁的纵向变形位移中计及了横向位移引起的轴向变形 ,并采用有限元方法和 Hamilton变分原理导出了系统的刚柔耦合一次近似的动力学方程。该方程充分计及了中心刚体的大范围运动与柔性梁的弹性变形运动的相互耦合 ,并采用一致的方法引入了阻尼因素。文中最后提供了一个比“动力刚化”问题更具有一般性的仿真计算反例 ,进一步说明了零次近似方法在处理某些刚 -柔耦合动力学问题时的缺陷 ,同时表明了由一次近似模型可得到正确合理的结论
