Abstract: According to the basic equation of dynamics, using FEM and NEWMARK implicit integration algorithm, an elastoplastic numerical analysis is made to analyze the efficiency of vibration isolating groove to the vibration caused by vehicle load. In order to reduce the effect of wave reflecting on border, finite element and semi-infinite element are respectively used to discrete the internal and border parts. The position of the vibration isolating groove and its depth and width are the three mainly considered factors. Finally, on the basis of the numerical calculation results, their effect laws are analyzed.

Key words: vibration isolating groove, vibration isolating efficiency, FEM, vehicle load, FWD load
