Rev 5.0 - Longitudinal Reinforcements
File Name: August23_KL_Rev5.0.wbpj
(Copied from: "July 1_TommyRev.wbpj")
Notes:
Focused on lowering stresses for Top 30 wall case
Added a total of 12 longitudinal reinforcement tubes to try to add more resistance to bending during impact
all 1” square tubing
Testing the effects of a greater wall thickness (0.113”)
Note: there are currently interferences with floor panels, changes can be made to the reinforcement placement later
...
Stress Results
(not done yet, running into errors - some tubes were split into tiny segments?)

Rev 5.1 - Longitudinal Tubes
I was able to implement the tube solution and fixed some contacts regarding the collision objects.

Failing only at joints
Ideas for reinforcements
Add gussets at each of these joints
Sheet metal might be overkill if we are trying to fix these stresses
Tubes might not be the best way to reduce stresses at joints
Side 60
...
Comments
A lot of stresses on the top catamaran
A lot of stress at the front passengers floor
Ideas for reinforcements
Sheet metal over these tubes
More tubes at these areas. Basically a sheet metal wall, but made up of tubes

This image shows that the stresses are lower when the sheet metal reinforcements are suppressed.

Comments
A lot of stresses on these longitudinal tubes
Adding the sheet metal reinforcement actually increases the stress
Ideas for reinforcements
More tubes in the longitudinal direction (front to back)
Note to self:
The back bar (collision object 11) is not compiling properly
contact is red and open
