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