A solid-body model of the rotor system of the turbocharge for light trucks is built. The influence of the oil film bearing support and the material internal damping of the rotor system is studied by using finite element method (FEM), the parameters of the rotor shaft diameter are optimized. The results show that the material internal damping of rotor and the oil film bearing support have complex influence on the dynamic behavior of the rotor and which reduces the running stability of the rotor.
