In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... En savoir plus
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... En savoir plus
This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... En savoir plus
This example model simulates the long-path echo of trumpet sounds reflected from a building 500 m away. The echo can only be heard at night because of the acoustic ray refraction in the atmosphere with different temperature profiles. The model is solved using the ray tracing in the ... En savoir plus
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... En savoir plus
This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... En savoir plus
This is a benchmark model to test the numerical algorithms in the area of multibody dynamics. This model simulates the dynamic behavior of the slider crank mechanism. This mechanism goes through singular positions during its operation. The acceleration at a point is compared with the ... En savoir plus
Piezoelectric microblowers are compact, lightweight air pumps with varying applications including electronics cooling and airflow related medical devices. The device consists of a PZT-brass diaphragm and a specially designed housing including a pumping chamber, air inlet and outlet ... En savoir plus
This model studies a small orifice located in a duct. The transmission and reflection coefficients of the system are computed in the presence of a bias flow using the linearized Navier-Stokes equations. For certain frequencies the transmission coefficient shows amplification (T>1). This ... En savoir plus
In microfluidic devices, it is a challenge to mix different fluids. One method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model, the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... En savoir plus
