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...
