| 摘 要： | 为了研究杆式旋转展开机构在展开过程中的动力学特性, 建立考虑中心杆柔
性的多体系统动力学模型, 并进行了理想工况下的数值仿真计算, 计算结果表明运动结果与
试验较为吻合; 最后进行了考虑工作方位、动力偏转、质量平衡等因素的非理想工况下的数值仿
真, 通过分析研究, 工作方位及质量平衡对系统稳定工作的影响更显著, 小角度范围内的动
力偏转的影响可以不计.

| Abstract: | A dynamics model of a rod-shaped rotational
expansion mechanism with consideration of the flexibility of the center
rod is developed for
studying the dynamic property in the expanding process. A numerical
simulation is carried out under an ideal operating condition. The kinematic
parameter in the computed results agree well with the test result. Finally a
simulation is carried out with considerations of operation
direction, dynamic deflection and mass unbalance. It is shown that
the influence of operation direction and mass unbalance
is much more important, and that of the dynamic deflection could be
ignored in the small angle area. |
