As an important component of the CNC milling machine, the stiffness and vibratory modal of spindle need to be analyzed in the process of design. In this paper, the above two performance parameters were analyzed by use of finite element method (FEM). For stiffness analysis model, the beam elements (BEAM4) and spring-damper elements (COMBIN14) were used. For modal analysis, the solid elements (SOLID45)...
The calculation of imbalance response plays an important role in the dynamical analysis of rotor-bearing system, the FEM is one of the methods that can calculate the dynamical response, and the ANSYS is a large finite element analysis software. This paper studies on the rotor test bed, and the supporting condition of the rotor-bearing is set in reason with the help of ANSYS. Dynamic parameter such...
