11.8.3.3 Loads from accelerated movements

Loads from accelerated movements

Figure 11.193 Generate Loads from Movements dialog box

This generator creates loads as a result of an acceleration or rotation that acts on specific objects of the model. The mass is determined from the self-weight.

In the Objects with Load dialog section, you can enter the numbers of relevant members, surfaces, or solids or select them graphically with .

You can define the Load Parameters either as an acceleration or rotation (angular velocity ω, angular acceleration α). With the button, you can determine the acceleration from the velocities that are available on two points.

In the Definition of the vector of acceleration dialog section, specify if the vector is related to a global axis or defined by two points. The vector can also be defined graphically by using the buttons.

Click [OK] to create the loads for the current load case.
