3. Project Goal Exploring 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.

4. Method of Analysis Structures 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.

5. Theoretical Background Von Mises Stress 1 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.

6. Current Structure Structure has angled support beams. Area 1 Loading 250 lbs - platform pallet jack 50 lbs – pallet 1100 lbs – ingredients used 1400 lbs total Area 2 Loading 100 lbs – flooring weight 200 lbs – operator 300 lbs total Area 3 Loading 250 lbs - platform pallet jack 50 lbs – pallet 1850 lbs – ingredients used 2050 lbs total 1 2 3

7. Current Structure Equivalent Stress Analysis Maximum stress was on the platform in area 3. 1 2 3 Very little stresses on the legs. 1 2 3

8. Current Structure Total Deformation Maximum deformation located in red..013487 in.

9. Structure w/o Angular Supports Area 1 Loading 250 lbs - platform pallet jack 50 lbs – pallet 1100 lbs – ingredients used 1400 lbs total Area 2 Loading 100 lbs – flooring weight 200 lbs – operator 300 lbs total Area 3 Loading 250 lbs - platform pallet jack 50 lbs – pallet 1850 lbs – ingredients used 2050 lbs total 1 2 3

10. Structure w/o Angular Supports Equivalent Stress Analysis Most stress in area 3. 1 2 3

11. Structure w/o Angular Supports Total Deformation Most deformation occurs on outside legs of area 3. 1 2 3

12. Structural Comparison Equivalent Stress Red area represents 500.54 psi. Less area of maximum stress. Red area represents 534.53 psi.

13. Structural Comparison Total Deformation Max. deformation:.013487 in Less total area in max deformation. Max. deformation:.014094 in

14. Conclusions Benefits 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 supports Slightly more deformation across total area of the platform.
