CONSTRAINTS APPLICATIONS

Constraints are required in many different types of dynamic systems. In fact, most dynamic systems do have constraints, which is why it is very important to be able to properly identify and apply them during analysis. A few examples of the ways constraints are applied are given below:

In beam bending and beam torsion, constraints come in as boundary conditions at the ends of the beam. Beam representations are often used in aeroelasticity for the analysis of wings and rotor blades.
In helicopter sling loads, the cable which attaches the load to the helicopter may be represented as a constraint.
A vehicle such as a car, airplane, or helicopter has many thousands of moving parts but they are all constrained to move in only a few degrees of freedom. The vehicle itself, however, is usually unconstrained.
