摘要:
通过ADAMS和I-DEAS建立空间展开桁架的柔性多体动力学仿真模型.比较了刚柔桁架展开过程中卫星姿态角及姿态角速度的变化,及柔性桁架的不同展开速度对卫星姿态角及姿态角速度的影响.通过对卫星在不同初始姿态角速度下,及在受到力矩脉冲作用下展开时卫星的姿态角速度影响的比较,说明了在这两种初始扰动下桁架展开运动的稳定性情况.对不同驱动角速度下桁架展开的仿真比较得到该桁架的失稳条件.
Abstract:
The dynamics simulation models of deployable truss structures were built by ADAMS and I-DEAS.The rigid and flexible trusses were simulated respectively.The dependences of the attitude angle degree and angle velocity of the spacecraft on the rigid and flexible situation in the deployment process and drive velocities loaded on the joints were derived.According to the definition of motion stability,the simulation results under the conditions of different initial attitude angle velocities and pulse torque funct...
