Spring applied breaks represent safety element that are deployed in mechatronics and robotics to ensure that the output shaft of a servomotor remains at a fixed position during special operational conditions. The present paper proposes a modeling and simulation approach for capturing the underlying structural characteristics of such assemblies, with the support of computer aided software. The design in discussion is inspired from an AC servomotor. AutoCAD 3D is used for representing each individual component as a solid structure. The complete assembly and preprocessing of the model for transient simulations is carried out with the support of ANSYS Workbench suite. The non-linear behavior of the breaking phenomenon is captured by deploying frictional contacts. Joints are added to materialize and constrain the motion of the mving elements. The results achieved are the total deformation and the Equivalent Von-Mises stress.
