This course will be offered during the third AND fourth quartile.|
After the course the student comprehends the principles of conceptual design of precision mechanisms and is able to recognize problem areas, to generate design alternatives and to make adequate choices.
After the course the student is able to...
Analyse, design and evaluate precision mechanisms with respect to stiffness:
Analyse, design and evaluate precision mechanisms with respect to degrees of freedom and constraints
Design, analyse and evaluate precision mechanisms based on flexure elements
Design and analyse precision mechanisms which inherently have hysteresis and microslip
Design and analyse precision mechanisms with bearings, rollers and webs
Design and analyse precision mechanisms with respect to dynamics and energy management
This course gives insight in the conceptual design of precision mechanisms used in products, tools and equipment. Characteristic to all precision systems is the high level of determinacy required. Predictable and reproducible behavior are key-qualities that can only be achieved when mechanics and control systems (if present) are carefully designed and robust to disturbances. Their mechanical design is the subject of this course. The insight in precision mechanisms enables the student to recognize problem areas, generate design alternatives and make the appropriate choices. Considerable attention will be paid to details, because these can be crucial and decisive for the quality of the design. Important principles for precision mechanism design which will be focused on during the course are: Designing for light and stiff mechanisms, exact kinematic constraint design, design of low-hysteresis mechanisms and designing precision manipulators.
Design for stiffness, prevention of play and backlash, design of elastic mechanisms, degrees-of-freedom, manipulation, friction, hysteresis and micro-slip, mechanisms based on rolling, belts and cables, energy management, special mechanisms.
