Hull and ama

 

 

 

 

CAD1

SolidWorks stress simulation on a CAD model of the proa. The model was created in SolidWorks. This simulation in particular involved studying how large forces on the Ama effect the crossbeam structure. Such forces on the Ama could be created by waves and water forcing the Ama to not only displace upwards but also twist. The areas of interest are the portions of the crossbeams that join the main hull. As can be seen by the red coloring, the largest stresses occur where the crossbeams meet the main hull which is expected. An extremely strong joint area is critical for the final proa.  In addition to the analysis of the joint areas, the simulation illustrates that this crossbeam design has a reasonable stress distribution, making the design itself more promising.
