Abstract:

Based on the Cartesian frame,the paper established a dynamics model of the linear array deployable structures based on scissor-like element.The motion constraint equations can be established by
constraints' conditions such as kinematic pairs.Using Runge-Kutta method for
numerical calculation,the laws of the structure,such as velocity and acceleration,
can be obtained in motion,and kinematic curve is also able to be drawn,
and then it provides the foundation of this structure of the application.
The results show that the linear array SLE in an process does not have consistent
level speed.
