180 Meshless methods and their numerical properties
Based on the simulation results, the pull-in voltages obtained by the RDQ
method closely match the literature values based on the experiments. It can
also be said that the RDQ method handles the nonlinear electrostatic force
eld well.
It is seen from Figure4.24b and Figure4.26b that the peak deection
equal to 7 μm of the beam is about 9% of the total length equal to 80μm
of the beam, which is a case of large deection. Therefore, the linear struc-
tural model, as given by Equation (4.55), may not be sufcient to solve
this problem correctly. However, it is adequate to capture the pull-i ...
