Improving Your Golf Swing with a Multibody Analysis

June 6, 2014

The outcome of a golf stroke is determined by the movement of the club head just prior to impact with the ball. Therefore, one theoretically could improve their golf swing via multibody analysis.

Modeling a Helicopter Swashplate Mechanism

June 14, 2013

A swashplate mechanism, used in a helicopter to control the pitch of the rotor blades, can be easily simulated using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables simulation of an assembly of flexible and rigid bodies, together with physical phenomena from fluid, heat, and electrical applications, among others. Here, we will show you a model to convey how a swashplate mechanism works and at the same time analyze the stresses and deformation in the flexible rotor […]

Double Pendulum Simulation Tutorial

May 22, 2013

Dynamic simulation of a double pendulum system can easily be performed using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables the mechanical simulations of assemblies of flexible and rigid bodies, often coupled with other phenomena such as from heat, electrical, and others.
