Abstract:

This paper identifies the bird’s material parameters automatically by an optimization searching method when bird’s constitutive model is selected. The method can replace the manual method which is troublesome, time wasting and subjective. A contactimpact coupling algorithm is applied to numerical simulation. The optimization objective is to minimize the square sum of percentage errors between test values and calculation results.
