Create Loads

Create sets and surfaces

Firstly, we create a new set named 'fixed-end', by clicking 'Tools > Set > Create' button.

Continue and click on the faces (red) of the part that is going to be fixed.

Repeat the operations above to create a new set called 'External load'.

Continue and select the two points (red) to be exerted force.

Then, we hide the frame using the button Remove Selected, only appearing airbags as the figure below.

Next, we create another set named 'air bag' by clicking 'Tools > Set > Create' button again.

Continue and select all the airbags as a set that is going to be constrained afterwards.

Then, create a surface also named 'air bag' by clicking 'Tools > Surface > Create' button.

Click 'Brown' to select the internal face of these airbags.

Create loads

Under the 'Step-1', create a load named 'pressure' and activate Pressure as the selected type for the step.

In the Region Selection window that appears, select the surface 'air bag' which we created earlier.

At the next window provide the pressure value to be applied in the airbags by setting Magnitude as 0.1 Mpa.

Next, we create a load of external force in 'Step-1' named 'External load' with type of Concentrated force.

Select set 'External load' which we create earlier.

Continue and set CF3 as 0.2 N exerted on the two points (red) at the manipulator's tip.

Then, create another external load named 'External load 2' in 'Step-2' with types of Concentrated force.

This load is implemented as a force in the opposite direction of the prior one, with a magnitude of 0.15 N (CF3 set as -0.15).

Set boundary conditions

Create a new boundary condition named 'fixed' in step 'initial' and select Symmetry/Antisymmetry/Encastre.

 

load-17.png

In the next window select set 'fixed end'.

And select ENCASTRE to fix the red regions.

Next, create new boundary condition named 'limited' in 'Initial', with the same property as the prior.

 

l

And select YSYMM to make airbags unable to move in y-axis.

Finally, we can check the load, boundary information in Load Manager and Boundary Condition Manager.
