Subject: Re: Undercarriage Bushes - Raplacement
From: "Area-51" <goldsteinindustrial@gmail.com>
So after doing some initial thinking and letting the vault of forgotten knowledge
murmur mumbles to me about "sintered bronze bushes" I decided to explore why
I have been looking at LG08 and LG07 thinking "those bushes are way too small
for that task"... So what happens within these moments? Area-51 happens...
Today the big switch to power up the laboratory was thrown over to the "ON" position
and the FEA work began with formulating and testing another digital model
of the Mono undercarriage; focusing on the oilite bushes.
Surprise surprise... Both LG08 and LG07 bushes both failed FEA stress testing at
just 1G with a 550kg AUW. In contrast LG05 bushes passed 1G stress testing through
to 3G loading. The assembly was stressed to 4G to assess material requirements.
Conclusion: incorrect material choice for component sizing resulting in accelerated
failure. However they have lasted for 800 landings over a 25 year period...
Will be opting for either C86400/300 manganese bronze instead of sintered bronze.
Thanks again for help with sizings and info'
