Modeling the Dynamics of a Gyroscope
Gyroscopes and spinning tops aren’t just old-fashioned toys. Using models of these 2 structures, we illustrate the remarkable properties of rotating bodies.
What Is Geometric Nonlinearity?
If you perform structural mechanics analyses, then you have most likely encountered the concept of geometric nonlinearity. But what exactly does geometric nonlinearity mean?
How to Model Hygroscopic Swelling
Hygroscopic swelling occurs in various sectors of industry, from wood construction and paper to electronics and food processing. Learn how to model this phenomenon in COMSOL Multiphysics®.
App: Improving the Payload Capacity of a Truck-Mounted Crane
Manufacturers and engineers looking to optimize the payload, or carrying, capacity of a truck-mounted crane can easily test parameters with a simulation app. Take a look at our demo app example.
Instability in Portable Washing Machines
A varied distribution of clothing can cause walking instability in both traditional and portable washing machines. Multibody dynamics analysis can be used to avoid this effect in machine designs.
Improving the Operational Lifetime of a Reciprocating Engine
Many of today’s motor vehicles rely on reciprocating piston engines as their source of power. Multibody dynamics analysis can be used to analyze the operation and performance of these engines.
The Motions and Mechanics of a Truck-Mounted Crane
The Truck Mounted Crane tutorial model analyzes the forces on the cylinders and hinges of a crane during an operating cycle, combining multibody dynamics and structural analyses.
Simulating Vibration and Noise in a Washing Machine
When designing a washing machine, you must account for a nonuniform distribution of clothing during operation. Simulation can be used to analyze vibration and noise in this household device.
