Iteration	Mass Setup	Mass Distribution	Scenarios	Max Stress	Figure #	Notes
1	No Mass		Side 60 Wall	64.193MPa	1
2	No Mass		Top 60 Wall	23.072MPa	2	Stress distribution looks a bit funky, see figure 3
3	No Mass
4	Only B.Box	Unchanged	Side 60 Wall	151.18MPa	4
5	Only B.Box	Unchanged	Top 60 Wall	56.273MPa	5
6	Only B.Box	See figure 6	Side 60 Wall	150.83MPa
7	Only B. Box, Pinball Region: all	“	“	149.63MPa	7
8	Same as above, pinball 750mm	“	“	150.48MPa		same max and min points as iteration 7
9	Same, pinball 250mm	“	“	149.71MPa		“
10	Same as above	“	Front 30 Wall	84.925MPa	9
11	Same as above, pinball 500mm	“	“	85.117MPa		same max and min as iteration 9

Figure 1: No mass, Side 60 Wall

Figure 2: No mass, Top 60 Wall

Figure 3: Top 60 Wall, odd result

Figure 4: Battery box only, Side 60 Wall

Figure 5: Battery box only, Top 60 Wall

Figure 6: 17 Tube configuration

Figure 7: results from figure 6, side 60 wall

Figure 8: Iteration 7 results

Figure 9: Front 30 wall with 17 tube distribution with 250mm pinball radius

All mass distributed on all tubes vs. Specific mass distributed on respective tubes

Front 30 Wall - All mass on all tubes

Max = 359.41MPa

Corresponding Mass Setup

Front 30 - Realistic Mass

Max: 305.73MPa

Conclusion: not a significant effect, 50MPa by drastically altering the weight distribution; but an effect nonetheless

Note, not sure how Tommy got the picture below (from chassis FEA advisors meeting)

This is what I get from the same sim in the same project: 2021-01-06(vehicle impact).wbpj
