Structural and Fatigue Analysis of a Car Wheel Rim
This example shows two structural analyses of a car wheel rim.
Firstly, the parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two solutions...
This is a model exemplifying how fluid-structure interactions can be modeled using COMSOL Multiphysics. Viscous forces and the system’s pressure impose forces to the surface of a structure. The deformation in the soft structure is not small and the fluid...
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets....
When modeling boiling flows, the mass transfer across the phase boundary, as well as the absorption of latent heat as the liquid evaporates, needs to be accounted for.
Here, a liquid is initially at rest above a thin layer of vapor, where the temperature...
In this model, continuous casting processing of a metal rod from melted to solid state is modeled.
The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to solid. This phase change causes momentum changes,...
Snap hook fasteners, where a hook is inserted into a groove, are common in the automotive industry, for example in the control panel of a car.
To obtain the magnitude of the forces necessary to insert and remove the hook, this model solves a nonlinear...
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems...
This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal...
People that use piezoelectric transducers are interested in phased-array microphone, ultrasound equipment, ink-jet drop actuators, drug discovery, Sonar transducers, bio-imaging and acousto-bio-theraputics. Basically anyone who is trying to create sound...
In this model, a diesel engine piston is studied at steady-state conditions, that is, at a continuous engine speed and load.
The combustion process at steady-state produces cyclic pressure loads and a high constant temperatures. These load conditions...
