Angular global loads in the Simulation workspace

Angular Global Loads are global loads which, when applied, affect all the parts or bodies of the Simulation model. They are used to represent the acceleration forces that act on a mass experiencing angular acceleration, or that is rotating at a steady angular velocity. The force is proportional to the mass of the material. A global load has no effect on a material with zero mass.

Note: Only one global load can be applied per study.

Angular Global Loads can be used in the following structural analyses:

static stress icon Static stress study

nonlinear static stress icon Nonlinear static stress study

modal frequencies icon Modal Frequencies study

thermal stress icon Thermal stress study

structural buckling icon Structural Buckling study

shape optimization icon Shape Optimization study

Use an angular global load to apply forces representing the following conditions:

Angular velocity: Such as the centrifugal force in a spinning wheel or centrifuge. This force acts radially outward relative to the axis of rotation.
Angular acceleration: Such as a wheel spinning at an increasing speed (accelerating). The angular acceleration force acts tangentially relative to the axis of rotation.

Acceleration can be positive (speed increasing) or negative (speed decreasing). For an object that is both spinning and either accelerating or decelerating, apply an Angular Global Load consisting of both velocity and acceleration inputs. The resulting load produces both a radial and a tangential component of force on each element in the model.
