La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.

Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.

Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.

Rotordynamic Analysis of a Crankshaft

See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... Per saperne di più

Modeling Vibration and Noise in a Gearbox: Bearing Version

This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... Per saperne di più

Shaft Vibration due to Gear Rattle and Bearing Misalignment

In a gearbox, vibrations due to gear rattling and bearing misalignment are well known sources of noise. In this example, two shafts connected through a pair of gears are considered. The shafts are supported on roller bearings at their ends. Initially, the driven shaft is unloaded and the ... Per saperne di più

Reciprocating Engine with Hydrodynamic Bearings

A single cylinder reciprocating engine supported on hydrodynamic bearings is studied. A starting torque is applied to bring the engine to required rpm. The loading torque is switched on once the engine picks up speed. After the start-up, the engine operates on its own driven by the ... Per saperne di più

Rotors Connected by a Spline Coupling

In this example, learn how to model two rotors connected by a spline coupling. The first rotor is a fixed cantilevered rotor and the second rotor is supported. The model assumes that only translational motion is coupled between the rotors through the coupling, while the rotations of both ... Per saperne di più

Thermal Stress in a Rotor due to Bearing Heat Loss

Hydrodynamic bearings generate heat due to the viscous losses in the lubricant. As a result, the temperature of the rotor increases causing deformation and thermal stresses in both the rotor and the bearing housing. This example shows how to model different physical phenomena that are ... Per saperne di più

Rotors Connected Through Helical Gears

In this tutorial model, learn how to model multiple rotors connected through helical gears using the Rotordynamics Module, an add-on product to the Structural Mechanics Module and COMSOL Multiphysics®. When modeling geared rotors, the presence of gears in the system induces the lateral ... Per saperne di più

Rotor Bearing System Simulator

This app demonstrates the following: Navigation system using toggle buttons in the ribbon and Back/Forward buttons in the settings window Selecting predefined or user-defined materials Using a table for input of geometry objects The app simulates a rotor bearing system consisting of ...

Vibration Control in a Motor Drive Using an Active Magnetic Bearing

Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

Simply Supported Beam Rotor

In this tutorial model, you will see how to set up eigenfrequency and transient analyses (using FFT) of a rotor with various mountings and bearing supports. The example illustrates how to use Campbell and Waterfall plots to find the critical speed. It also demonstrates the range of ... Per saperne di più
