Modal analysis of high-speed spindle based on ANSYS

Modal analysis is an important step in optimal design of the spindle. Speedy cotton spindles of JW.D3203 are studied in this paper. The structural features of the spindle are described. ANSYS finite element analysis software is used for modeling of the spindle. Setting material properties, defining element type, meshing, and determining the boundary conditions are done before the top ten mode figures of spindle are gotton. The natural frequency and critical speed are gotton. Resonance phenomena is avoided when the speed of spindle reaches the critical speed. The simulation results have a good guide for structural optimization of the spindle.
