Abstract

The drop test analysis by using finite element method (FEM) needs effective techniques to achieve solutions within reasonable computational time. Therefore a global-local (GL) model is suggested in this work to reduce the computation time of the whole solution process with a reasonable accuracy. The proposed GL method is used to analyze a large-scale finite element TV model with complex and detailed components. The possibility of partial breaking of TV undergoing impact-contact condition is discussed. It also shows that the impact problem of TV finite element model with complex and a large number of detailed components in impact problem can be solved with an existing software within reasonable computational time. The Hertz's theory is also used in this work to reduce the impact force of the original model by changing certain properties. The results obtained through different parameters are presented and discussed.
