Research on the FE-Model of a Diesel Engine Body

In this paper,a method for establishing a finite element model (FE-model) of a diesel engine body was explored.A relativity analysis method was proposed between the parameters of FE-model and of measurement experimental,i.e.,a relativity analysis was carried out according to the response differences between numerical finite element computing and experimental results.Hence the reliability of FE-model could be improved by repeating the above procedures.Therefore,an efficient resolution was reached to improve the reliability of FE-model for a diesel engine body.
