Steel pipelines are often subjected to complex stress/strain conditions in the oil and gas industry. Additionally, pipes are subjected to significant longitudinal strain due to soil movement. For the elastoplastic stress simulation, the Solid Mechanics interface is used with the small ... En savoir plus
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... En savoir plus
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 ... En savoir plus
Differential inductance is relevant when a low-frequency electromagnetic system includes magnets, nonlinear magnetic materials, and moving parts. These models present examples of computing the differential inductance and using these within simplified lumped models. To learn more about ... En savoir plus
This model provides you with tools to build a variety of mixers by combining two common types of vessels with two types of impellers. The mixers are baffled flat and dished bottom vessels with either pitched blade impellers or Rushton turbines. The model includes three examples using the ... En savoir plus
This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... En savoir plus
In this example water ponded in a ring on the ground moves into a relatively dry soil column and carries a chemical with it. As it moves through the variably saturated soil column, the chemical attaches to solid particles, slowing the solute transport relative to the water. Additionally ... En savoir plus
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 ... En savoir plus
This model simulates electrical breakdown in an atmospheric pressure gas. Modeling dielectric barrier discharges in more than one dimension is possible, but the results can be difficult to interpret because of the amount of competing physics in the problem. In this simple model the ... En savoir plus
When electrons are emitted from a heated cathode in a plane parallel vacuum diode, they contribute to the space charge density in the diode, which in turn affects the electric potential distribution. If the potential difference between the cathode and the anode is not sufficiently large, ... En savoir plus
