Generating Loads from Motions

With RFEM, you can generate member, surface, or solid loads resulting from motions. Thus, for example, braking or acceleration forces can be generated automatically from linear movements or from rotational movements on a structural system.

In the present example, the structure is loaded by radial forces due to rotational movement. The angular velocity should be 10.0 rad/s. The radial force is calculated as follows:

Fr = r ⋅ ω² ⋅ m

This results in a maximum axial force in the members of:

Fr = 1.0 m ⋅ (10 rad/s) ² ⋅ 79.91 kg = 7,991 N ≈ 8 kN
