| Abstract |
A kind of novel 2‐DOF micromanipulator is
designed and analysed based on the two scales of level
amplifier principle, which adopts the flexure hinge to
replace the traditional hinge. The kinematics, static and
dynamic modelling are established, and the input
stiffness and actual amplification ratios are calculated.
Meanwhile, the finite element analysis (FEA) is applied in
order to validate the calculation by using ANSYS
software. Then, the theoretical, calculated and simulated
values diagrams are compared. Thereafter, the stress and
the natural frequency of the stage are also analysed to
optimize the platform dimensions. Parasitic motion
values are calculated and analysed, and their values are
compared in a diagram. The Particle Swarm Optimization
(POS) is applied to design and optimize the structure
parameters, and finally the optimal structure parameters
are obtained and the values of parameters are used by the
finite element model (FEM). In addition, a dynamic
equation and a suitable control flow chart are designed
for the mechanism, and the control strategy is proposed
accordingly. Finally, the simulation analysis of the stage
control adopting the MATLAB software is performed. |
