Název v původním jazyce

Modification of the double-ellipsoid heat source model by simplex method

Popis výsledku v původním jazyce

Despite the fact that fusion welding simulations have been used for over 20 years, their wider application has become evident only in the last 4 years. The reason is that there are both high requirements on quantity and quality of the input material data, and mainly high requirements on the accurate definition of the heat source model from which the non-stationary temperature field and temperature gradient are derived. For the conventional fusion welding methods simulation (except for the laser and electron beam), the double-ellipsoid heat source model is commonly used. However, a description of such a heat source model depends on many variables. The method that is presented in this paper could be used for the heat source parameters optimization. The method is based on fitting the computed weld pool shape to the measured one. It is a recurrent process using a simplex optimization method.
