Today the numbers on mod-xx were run through the trap. Short story 50% reduction
in component stress and force required at the operator end.
Both factory and mod-xx had the same parameters applied along with gravity to
factor
in the torque of the swing arm's mass. LG12 undercarriage lever has been
modelled using 4.0mm 1020 sheet steel.
At close out of the undercarriage retraction the factory setup delivers a 30200
Nm moment from LG08's axis to the operator handle while mod-xx delivers 13600
Nm.
Force required in the X direction (forward moving) at the operator handle for
the
factory setup is 700 N while mod-xx requires 320 N.
Tension force required at the bungee to reach zero mass balance at of the L02
undercarriage
arm is 860 N
The assembly model received a vertical force of 100 N at the wheel axle line and
gravity factor... bungee tension was not added to either test model.
This concludes this Obsidian File chapter to further discussion.
Images included for the technically astute.
