Moment loads in the Simulation workspace

A Moment load is a twisting load that attempts to rotate a body perpendicular to the designated rotational axis, to simulate the effects of a torque on your model. The Moment load is located directly on a model face. The Remote moment load is located at a point in space, instead of on the model.

The results obtained with moment loads are the same no matter where the moment load is located, as shown by the von Mises stress results in Figure 1. Use a Remote moment load when you want to be able to visualize the moment load.

Effect of moment location

(a) von Mises stress result with a Moment load applied to the two inside faces	(b) von Mises stress result with a remote moment load applied to the two inside face from a location in space between the two blocks	(c) von Mises stress result with a remote load applied to the two inside faces from a different remote location

Figure 1: showing that the stress experienced by the two blocks is the same, regardless of the location of the moment load.

In Fusion, the default direction of the moment axis is normal to the selected face. Once you select the relevant faces, the centroid of the selected faces is calculated. The axis of the moment is parallel to the direction you specify, and the axis passes through the centroid. The program applies a force distribution along the faces that results in the specified moment magnitude.

The moment magnitude is distributed on a prorated basis among all the faces you select. For example, if you select four faces of the same size and enter a magnitude of 400 lb-ft, you're applying the load of 100 lb-ft to each face. The total applied moment is 400 lb-ft (100 lb-ft * 4 faces).
