1. Development, construction and design
on the basis of
• FEM-calculation
• FKM-method
Copyright by Pantecnica 28
2. Damage Calculation
Is Performed to
▪ predict lifetime of one or multi axial loaded rubber-to-metal-bonded parts
▪ shorten dynamic component test
▪ eliminate non-damaging load rates from load collective
▪ calculate load collective with very high cycles-to-failure which cannot be tested within a reasonable period of time
This kind of calculation serves as prediction and has to becombined fundamentally with a shortened component test forverification.
