THE STUDY OF THE KINEMATICS OF THE LIFTING-LOWERING MECHANISM OF THE SMA-2 POWERED ROOF SUPPORT USING COMPUTER SOFTWARE.

The shield of the SMA-2 utilizes a quadrilateral mechanism with a corner cylinder generating a lemniscate. The synthesis of the quadrilateral mechanism, its geometric and kinematic analysis in correlation with the geometry and kinematics of the entire support, raises challenging analytical issues. For this reason, in the present work, we have theoretically and practically analyzed the geometry and kinematics of the mechanism, demonstrating the utility of using computer software for modeling and simulation in addressing these problems.
