An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Mehr lesen
Freefrom optics has generated renewed interest due to advances in fabrication and manufacturing technology. In this Application Library example, we are going to look at a specific design called the Alvarez lens where two complementary conic surfaces are shifted laterally with respect to ... Mehr lesen
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

The powder compaction process is becoming common in the manufacturing industry, thanks to its potential to produce components of complex shape and high strength. In this example, the compaction of iron powder to form an axisymmetric rotational flanged component is analyzed with capped ... Mehr lesen
Micromirrors are used in certain MEMS devices to control optic elements. This model of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping of ...

Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... Mehr lesen
This model simulates the mechanism of a differential gear used in cars and other wheeled vehicles. A differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when a vehicle turns in order to allow the wheel that is traveling ...

A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Mehr lesen
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... Mehr lesen
This example illustrates the modeling of a sequential manual transmission, where the gears are selected sequentially with the help of a rotating drum. The shift drum has two grooves of specific profile carved around the circumference. As the drum rotates, the grooves on the drum guide a ... Mehr lesen
