• Matt - distribute the entire mass of the chassis onto the entire thing

  • allocate the additional masses and distribute to the entire chassis

Tom - time crunch?

• run it again - same constraints - run no mass

  • if mass is not the concern, start looking at how it is constrained can be a factor

  • eliminating major factors and narrowing the potential factors

    • Idea: remove the complexities and analyze it on a simple level

  • suspect that point masses could be sources of the problem

    • test it unloaded

    • test it masses distributed across the chassis

  • simplifying your model and still missing by a wide margin, there is something potentially wrong from the fundamentals (how you sim it)

Summary of Action Items

As per shalin and matt:

• try simulating just the chassis for the worst case orientation with no masses

  • then keep adding masses to check for exponential increase (unreasonable)

  • Shalin’s suggestion of L-shaped passenger (geometry+density =80kg)

  • distribute the additional masses of the entire vehicle across the entire chassis and see how that runs

• make presentation and send to advisors for offline review (see unclosed items)

  • take a look at kimberly’s studies on making the bar go into the chassis with the chassis stationary

  • also take a look at doing what MSXII did for having the contact between the collision object and the chassis be frictionless

    • frictional and sliding contact; one node closes to the collision object near the centre to prevent it from sliding

Unclosed Items

Fixing the chassis and running the bar into the chassis

friction contacts

^^ weren’t able to conclude or no ground basis of justification

• reached to that point – didn’t reach out to advisors for review

  • that is the time to bring in the advisors for review
