Abstract
Component strength of the piston can be ensured in various ways. Finite element analysis (FEA) is typically used for this purpose on a regular basis. A strain gauge measurement or pulsator test is used less often. In mathematical component analysis, all relevant thermal and mechanical loads, shrinkage, joining, and residual stresses can be analyzed. The basis of the FEA model is the ideal contour as outlined by the CAD dataset. The computational and strain gauge measurement results are analyzed using temperature-dependent material fatigue data. This is based on statistically confirmed test values, determined using test bars taken from pistons and artificially aged at the test temperature prior to testing. This ensures that the least favorable material parameters are taken as a basis.
