Solid Gold Kraken

Last crawled date: 1 year, 10 months ago

75.51 % decrease in mass from original part.

I have removed the fillets near the bolt holes as they were causing drastic changes to KSI.

This is the same design as my other KRAKEN V4 submissions, however it has not been lightened in any way so as to pass all FEA tests, regardless of how the constraints are setup. I am using 6 different types/combinations of constraints in order to get the widest spread of data. This simpler design offers a higher FOS than the lightened versions, although all designs have an FOS over 1.


ORIGINAL PART
Mass = 2111.647 grams

THE SOLID KRAKEN V4
Mass = 517.011 grams
