A FINITE-ELEMENT ANALYSIS OF THE IMPACT CONTACT PROBLEM OF A PORTABLE TELEPHONE USING I-DEAS AND ADINA

A finite element analysis has been carried out to simulate the phenomenon of a portable telephone that falls and collides with a rigid surface. The new I-DEAS Master Series has been used to create the complicated geometry and finite element mesh for the portable telephone model. The finite element data obtained in I-DEAS is converted to input data for the ADINA system by TRANSOR, an interface program between I-DEAS and ADINA. The large scale finite element model has been solved by the iterative solver on a SUN 4/10 engineering workstation. Interesting results at various stages are: free-fall, impact-contact and, rebound. The possibility of partial breaking of the portable telephone undergoing the impact-contact condition is also discussed.
