| Abstract: | Dynamics analysis of flexible structure is an important research issue for flexible structure subject and the deformation of flexible parts has direct impact on the security and reliability of the system. This paper focused on the beam typed flexible element characteristics of SMA flexible torsion actuator and applied the finite segment method to establish its discrete analysis model. This paper took advantages of ADAMS software in the analysis of multi-bodies system dynamics, utilized ADAMS macro command to establish the finite segment discrete model of SMA flexible torsion actuator. Thus, this method transformed the dynamics analysis issue of flexible structure into the one of multi-rigidity-bodies, which can well be analyzed for its dynamics characteristics. |
