Samsung Amps Up Loudspeaker Designs with Simulation
Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…
Optimizing Lubricated Systems with Numerical Simulation
Experts at SIMTEC designed a lubricated mechanical contact using numerical modeling and built an application for optimizing the use of lubrication in rolling and sliding bearings.
Predicting the Unpredictable: Simulating Earthquake Mechanics
In case of an earthquake, people regularly practice hiding under their desks. Another way to prepare? Using response spectrum analysis to determine the structural stability of a building subject to this type of seismic event.
How to Automate Meshing in Frequency Bands for Acoustic Simulations
There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.
Analyzing Vibrations in Rotating Machinery Due to Bearing Misalignment
You can use structural analysis to compare the angular velocity, axial displacement, and bearing reaction moment on the shaft for rotating machinery with aligned and misaligned bearings.
Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.
Frequency Response of Mechanical Systems
Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.
How to Use Lumped Elements to Model a Mechanical System
Modeling a large, complex system? You may want to simplify configurations in the model setup to better understand it, but how? Enter the Lumped Mechanical System interface in COMSOL Multiphysics.
