Reachable and usable workspace of the macro motion As the good elastic nature of the selected material of wide-range flexure hinges, the workspace of micro motion only depends on the limits of PZT actuators. Considering the different characteristics between flexure hinge and conventional mechanical...

The mathematical formulation accounted for tangential motions of rolling elements and inner and outer races with the sources of nonlinearity such as Hertzian contact force and internal radial clearance. The nonlinear stiffness is obtained by the application of Hertzian elastic contact deformation...

Results show that, with proper sizing and specifications, the cantilever beam control mechanism requires relatively...

...Jimmy Issa; Ranjan Mukherjee; Alejandro R. Diaz A strategy to remove energy from finite-dimensional elastic systems is presented. The strategy is based on the cyclic application and removal of constraints that effectively remove and restore degrees of freedom of the system. In general, application...
