Gear rattle and bearing misalignment are common sources of vibration and noise in gearboxes. This example considers two geared shafts supported by roller bearings. Backlash causes intermittent tooth contact and induces shaft vibrations when the driven shaft is unloaded and the driving ... 詳細を見る

A helical antenna has two major modes. One is normal mode and the other is axial mode. When the helical antenna is operating at the normal mode, its far-field radiation pattern is similar to the torus shaped pattern of a classic dipole antenna. At the axial mode, the helical antenna is ... 詳細を見る

This model demonstrates how to design a beam without low Eigenfrequencies by combining the Density Model feature in the Topology Optimization interface with the Stationary Then Eigenfrequency study step. 詳細を見る

In this example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in wrinkling of the membrane. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The ... 詳細を見る

This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. 詳細を見る

This is a tutorial model that demonstrates how to use mesh parameters such as Minimum element size Resolution of curvature Resolution of narrow regions Maximum element growth rate The instructions also detail how to access the mesh statistics and how to create a mesh plot. 詳細を見る

This model analyzes an RF MEMS switch consisting of a thin micromechanical bridge suspended over a dielectric layer. A DC voltage greater than the pull-in voltage is applied across the switch, causing the bridge to collapse onto the dielectric layer with a resulting increase in the ... 詳細を見る

In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... 詳細を見る

This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... 詳細を見る
