Helicopter Swashplate Mechanism
Application ID: 14647
This model illustrates the operation of a swashplate mechanism used in helicopters to translate the input of helicopter flight control into the motion of the rotor blades, and hence controls the orientation of the rotor blades.
In this model, the rotor blades are modeled as either rigid bodies or flexible bodies in two different cases. All other components are assumed to be rigid bodies. Stress and deformation in the flexible rotor blades caused by the rotation and applied dynamic lift force are analyzed. An eigenfrequency analysis, where the mode shapes corresponding to the bending and torsion of the rotor blades are found, is also performed.
This model example illustrates applications of this type that would nominally be built using the following products:Multibody Dynamics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
