Simulation Overview Solid Edge Simulation is a fully integrated package enabling designers to run the following types of simulation studies: Beam Linear Static Steady State Heat Transfer Buckling Modal (Vibration) As well as combinations of multiples of these Page 4
Solid Edge Simulation No matter what type of Simulation study you need to run, Solid Edge provides a consistent experience for setting up and executing studies Consistent status feedback on when studies are ready/what steps are needed Only providing users with commands that are pertinent to that type of study All while leveraging Femap and Nastran Industry leading simulation technology Page 5
Solid Edge Simulation Beam Studies Beam Studies Measures stresses and displacement from loads and constraints applied to beam elements Very fast solve times, as many of the steps are automated (such as connections) Let s see an example! Page 6
Solid Edge Simulation Beam Studies Open Engine Hoist.asm from the Simulation & Optimization folder Once open, change the display configuration under the Home tab to Frame components Turn off Perspective on the View tab as well Page 7
Solid Edge Simulation Beam Studies On the Tools tab, click on Frame Extend out the Simulation Edge Bar and pin it on screen Right click on Simulation and select New Study Page 8
Solid Edge Simulation Beam Studies On the Study type Leave it as linear static On mesh type leave as beam (the only option available) Click OK Next, select all elements on screen Notice, only beam elements can be selected, so the casters and the hinge at the top are left out Right click to accept the geometry (make sure all of the support beams are selected as well) Page 9
Solid Edge Simulation Beam Studies Now that the geometry has been selected, we see in our Edge Bar that one of the pieces of the status pie is green Next we need to add loads Right click on loads and select Create Structural Load and then Force Change the input method from Curve to Node and create a downward force on the end of the load bearing beam Set load to 20,000N Right click to accept Page 10
Solid Edge Simulation Beam Studies Next, Constraints Right click on constraints>create New Constraint>Fixed Change the input method to Node again Create a fixed constraint on each node associated to a caster wheel Right click to accept Page 11

Solid Edge Simulation Buckling Analysis The next type of study we ll explore is Buckling Analysis Buckling analysis is a necessary an important part of design validation when working with long, thin objects such as beams Often times when validating designs, buckling will be run alongside a linear static analysis to determine which type of failure will happen first Let s take a look! Page 51

Solid Edge Simulation Buckling Analysis Solid Edge provides you with the eigenvalue of each leg where it would fail due to buckling Cycling through the different buckling values for each frame member, you can see that the first failure value is the lowest, meaning that the framework would buckle at a value of 23,420N As you cycle through the values, you can see which legs would buckle at which value Page 62
Solid Edge Simulation Buckling Analysis Once you have your minimum eigenvalue for buckling, you can compare that to a linear static beam analysis to find the max stress the members could take, and the lowest of the two would be where your first failure is most likely to happen. Of course, if a requirement is made to strengthen the beams, they can easily be changed and the study rerun with no rework on the analysis Page 63
