Considerations to Keep in Mind:
Keep track of weight
Standard weight that dynamics designs using is 720 kg.
Calculate weight of tubes before adding the new tubes. Then calculate weight of tubes after new tubes are added. Calculate percentage difference. <5% difference is likely not a large concern
Remember the complications in regards to welding.
Should review and measure out chassis before finalizing tubes order
Chassis Before Any Modifications:
ASC Regulations Requirements:
Quick Overview of Vehicle Collision Loading Scenarios:
See Appendix F of ASC Regs 2021 for more details
First Reinforcement Attempt
General Max Stresses:
Loading Scenario | Approx. Absolute Max. Stress (MPa) |
---|---|
Front Bar | 220 |
Back Bar | 420 |
Side 30 Wall | 1050 |
Side 60 Wall | 750 |
A Pillar | 1300 |
B Pillar | |
A lot of stress in the front half floor area. Will likely add more tubes on the lowest floor level shown in pink
