The structural dimensioning and strength calculations have been performed for the new
“Electric Water Cleaning Catamaran type HE 126” (HIPPO) – workboat intended for water pollution cleaning.
Equivalent von Misses stress distribution in frame hull (made of aluminum alloy) is below allowable stress limit 160 MPa
Weight reduction percentage is summarized in Table C1.
|FEM Model Weight [kg]||Weight of frame spacing||Weight Reduction %||Max von Mises Stress [MPa]|
|Basic Model A||1048.8||209.76||N/A||N/A|
|Model C1||933.14||188.63||10.07||108 < 160 (limit)|
|Model C2||905.5||181.10||13.66||121 < 160 (limit)|
