Design of 3-DOF parallel manipulators for micro-motion applications
(2009-08-01)
This thesis presents two unique micro-motion parallel kinematic manipulators (PKM):
a three degrees of freedom (3-DOF) micro-motion manipulator and a 3-DOF micro-motion
manipulator with actuation redundancy. The 3-DOF ...
Thermal performance analysis and geometrical optimization of automotive brake rotors.
(2008-07-01)
The heat dissipation and thermal performance of ventilated brake discs strongly depends on the aerodynamic characteristics of the air flow through the rotor passages. In this thesis, the thermal convection is analyzed using ...
