    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' Read this topic online here: http://forums.matronics.com/viewtopic.php?p=515341#515341 Attachments: http://forums.matronics.com//files/9fa1f6e0_690b_4bda_99ee_879abef149ce_139.jpeg http://forums.matronics.com//files/d163f5f1_ce0c_496b_8fd3_078b62e7f6ca_537.jpeg http://forums.matronics.com//files/b9e31da5_4020_4d52_8c2a_2de76d7a9f6d_159.jpeg
