基于ANSYS软件的大型伸缩回转平台的振动模态分析

Vibration Modal Analysis of Large-scale Retractable Rotary Platform Based on ANSYS Software

针对低速大型回转平台,借助ANSYS有限元分析软件,对平台各离散典型位置进行模态分析,采用离散拟合连续的方法,计算出回转平台各典型位置状态下的固有频率和振型,对大型回转平台低速连续可靠性工作提供了重要的设计基础。

Aiming at the large-scale,lower-speed retractable rotary platform,the paper proceed analysis of each scattered typical position at platform with FEA software ANSYS as well as calculated the natural frequencies and vibration type under each typical position of rotary platform.Thus provided important design basis for the large-scale,rotary platform with lower-speed reliable continuous working.
