| Abstract: | Gear, as the most important mechanical transmission part, has been widely used in variousfields. It is of great significance to make a systematic analysis of gear. This paper proposed a finite el-ement modal analysis method based on ANSYS for cylindrical gear. Firstly, a three-dimensional mod-el of cylindrical gear was created, and then meshing and finite element analysis model based on attrib-ute selection was established. The inherent frequency solving was completed by a set of solving so thatfour order modal vibration modes of cylindrical gear could be obtained. The results could effectivelyprevent the occurrence of resonance hazard and had important reference value for the research, devel-opment and design of gear. |
