Mesa elevatória de mecanismo tesoura com acionamento por fuso em posição central: análise dinâmica em ferramenta CAE

Abstract

This paper aims to contribute to the literature on the design and analysis of scissor lift tables or pantograph tables moved by a spindle actuator. Although there are many studies on lifting mechanisms with hydraulic piston drive, a gap was identified in relation to those with screw actuator. An analysis of the forces in the joints of the lifting mechanisms of these machines was performed using the Rigid Body Dynamics and Static Structural modules of the Ansys program. This first module was used for the simulation of the dynamics of multibody systems, while the second module was used for the analysis of the deformation caused by the forces resulting from the movement, in order to validate the rigid body hypothesis for the cases studied.
