Predicting the Stability of Rotor Systems with the COMSOL® Software
Instability in a rotor system can lead to catastrophic failure. Fortunately, engineers can predict the stability of rotor systems by performing stability analyses with the Rotordynamics Module.
Evaluating a Turbocharger Design with Rotordynamics Analysis
Like a “turbocharged” cup of coffee, an actual turbocharger also increases speed, but in the operation of a combustion engine, not how fast your morning cup wakes you up.
How to Model a Cam-Follower Mechanism
Watch a series of animations that show the different types of cam-follower mechanisms before learning how to model them in COMSOL Multiphysics®.
Finding Answers to the Tuning Fork Mystery with Simulation
If you strike a tuning fork and hold it against a tabletop, the peak frequency of the emitted sound doubles. Is there a physical explanation for this “tuning fork mystery”?
Analyzing Vehicle Suspension with Multibody Dynamics Modeling
How much damage can a pothole do to a car? Automotive engineers can set up lumped mechanical systems in COMSOL Multiphysics® to analyze vehicle suspension technology.
How to Model Roller Bearings in COMSOL Multiphysics®
Roller bearings are one of the most commonly used industrial components, found in gearboxes, conveyors, motors, and rolling mills, among other devices. Learn how to model this part in COMSOL®.
Analyzing the Viscous and Thermal Damping of a MEMS Micromirror
Micromirrors are efficient and inexpensive. Here, we go over 2 types of analyses for a MEMS micromirror design, frequency-domain and transient, using the COMSOL® software.
What Is the Physics Behind a Counterweight Trebuchet?
A counterweight trebuchet, a siege weapon commonly seen in movies set in the Middle Ages and fantasy worlds, also happen to be an interesting multibody dynamics problem.
