Flexible multibody modelling for the mechatronic design of compliant mechanisms
In high precision equipment the use of compliant mechanisms is favourable as elastic joints offer the advantages of low friction and no backlash. To satisfy exact constraint design the mechanism should have exactly the required degrees of freedom and constraints so that the system is kinematically and statically determinate. For this purpose we propose the following kinematic analysis using a f...
متن کاملApplication of Flexible Multibody Modelling for Control Synthesis in Mechatronics
The models used in the conceptual phase of the mechatronic design should not be too complicated, yet they should capture the dominant system behaviour. This includes the computation of natural frequencies and mode shapes in a relevant frequency range. For the control system synthesis the low frequent behaviour up to the cross-over frequency needs to be known. Furthermore, the closed-loop system...
متن کاملA Screw Theory Approach for the Conceptual Design of Flexible Joints for Compliant Mechanisms
This paper presents a screw theory based approach for the analysis and synthesis of flexible joints using wire and sheet flexures. The focus is on designing flexure systems that have a simple geometry, i.e., a parallel constraint pattern. We provide a systematic formulation of the constraint-based approach, which has been mainly developed by precision engineering experts in designing precision ...
متن کاملFlexible building blocks method for the optimal design of compliant mechanisms using piezoelectric material
This paper presents a new method to optimally design active compliant mechanisms. It is partly based on a flexible building blocks method called FlexIn, which had been developed at the French Atomic Energy Commission (CEA). This method uses an evolutionary algorithm approach to optimize a truss-like structure, made of an assembly of passive and active piezoelectric building blocks from two spec...
