Abstract
The present article discusses about the modeling of S shaped flexure mechanism built with double parallelogram manipulator (DFM) as building blocks. It generates motion between fixed support and motion head. It is built is single monolithic and compact in design as compared to rigid linkage. The finite element analysis is carried out in ANSYS15. The experimental test is carried out on the flexure mechanism integrated with dSPACE DS1104 R & D controller. DFM consists of actuator, optical encoder and DAQ system. The values obtained are in close match with FEA results. The voice coil motor is actuated by Linear Current Amplifier (LCAM) which get inputs as amplitude and frequency. The moment of the mechanism is detected by optical encoder and gives analog voltage to the output moment of the shaft. In applications such as nanometric positioning, the high-quality motion quality of flexures so strongly minimizes any limitations that most existing nano-positioners are basically based on flexures. An additional advantage of using flexures is that the trouble of assembly can be minimized by creating the mechanism monolithic. This makes flexures essential for micro-fabrication, where assembly is mostly tough, or even impossible. Thus, despite small range of motion and a important performance compromise between the DOF and DOC, flexures remain important machine elements.
