This example illustrates the modeling of an induction motor in which eddy currents are induced in the rotor by time-harmonic currents in the stator windings and by the rotor rotation. The induced currents interact with the magnetic field generated by the stator coils to produce the ... En savoir plus
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... En savoir plus
This example illustrates the modeling and dynamic analysis of a three-cylinder reciprocating engine. The model combines rigid and flexible components to investigate engine performance and the stresses generated during operation. The analysis helps identify critical components and ... En savoir plus
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger as soon as a ... En savoir plus
This model simulates the mechanism of a differential gear used in cars and other wheeled vehicles. A differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when a vehicle turns in order to allow the wheel that is traveling ...

Chain drives are used to transmit power between shafts separated by a distance. This example demonstrates the 3D modeling of a roller chain sprocket assembly consisting of a roller chain wrapped around two elastic sprockets. The motion of one sprocket is transmitted through the chain to ... En savoir plus
Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... En savoir plus
In this example, the dynamics of a hopping hoop is simulated. A rigid rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. The effects of different parameters like initial velocity and friction are explored. You ... En savoir plus
Roller conveyors are commonly used in warehouses, manufacturing units and baggage handling applications to transport objects from one place to other by gravity, power, or manually. A typical roller conveyor consists of an array of moving rollers arranged either in a straight or curved ... En savoir plus
This tutorial application demonstrates how to model a hinge joint between two bodies in COMSOL Multiphysics. It also demonstrates various features available for joints, including Constraints, Locking, Spring, Damper, Prescribed Motion, and Friction. Many real structures can be ... En savoir plus
