电梁
1.NODAS is a library of a series of low-level elements (2D, 3D beams, nonlinear beams, anchors, plate masses, electrostatic gaps, combs, eletrothermal beams, et al). The lumped parameterized behavioral models are implemented in MAST, which is an analog hardware description language.
3.Vibration of a micro beam structure under the nonlinear electric field force in MEMS is studied.
4.accelerates a continuous beam of electrons to high speeds by means of the electric field produced by changing magnetic flux.
5.③Combining with simulation by CoventorWare, the methods of using different thickness of grating margin, foursquare electrode, laddering electrode and thinner cantilever can increase the optical active area from 50% to 60%, 70%, 75%, 85% respectively.
6.The weak resonant signal was picked up by piezo-resistor Wheatstone bridge designed and fabricated on the silicon micro-cantilever.
7.Considering the influence of electrostrictive nonlinear piezoelectric effect, electroelastic nonlinear piezoelectric effects and geometric nonlinearity, the mathematical model of piezoelectric laminated beam was obtained.
8.Theoretical calculation results indicate that the natural frequency is proportional to the width of silicon beam, increased nonlinearly with the rake angle of oblique beam, and reduced nonlinearly with the length of silicon beam.
9.The electrical resistance change of CFRP bar is about 2.54%～6.87% at concrete beam failure.
10.The elastic stress self-monitoring of the key sections of carbon fiber reinforced smart concrete beams can be achieved based on FCER-ECS correlation curve obtained from experiment.
