Project GoalExploring installation

of second block icing stand.

Analyze the current stand under normal loading conditions.

Analyze stand without angled support beams under normal loading conditions.

Compare results.

Method of AnalysisStructures were originally drawn in ProE and

saved as .IGES files. Structures were then imported into ANSYS Workbench for analysis.

Once geometry was imported, fixed supports and loading conditions were added.

Structural Analysis was completed.Von-Mises stresses.Total Deformation.

Comparative analysis of two structures.

Theoretical BackgroundVon Mises Stress1

The Von Mises criteria is a formula for combining these 3 stresses into an equivalent stress, which is then compared to the yield stress of the material.

If the Von Mises Stress exceeds the yield stress divided by a safety factor, then the material is considered to be at the failure condition.

Current Structure Structure has angled support

beams. Area 1 Loading

ConclusionsBenefits of angular supports:

Equivalent Stress Area exhibiting maximum stress was reduced. Maximum stress reduced by approximately 35 psi.

Total Deformation Area exhibiting maximum deformation was reduced.

Detriments of angular supportsSlightly more deformation across total area of

the platform.
