基于CATIA的DSJ80/40/2型带式输送机传动滚筒模态分析

Modal Analysis of the Driving Drum of DSJ80/40/2 BeltConveyor

为了研究滚筒的固有频率,以DSJ80/40/2型带式输送机传动滚筒为研究对象,基于CATIA软件对其进行了模态分析。分析得到滚筒的四阶固有频率与振幅,第一、第二、第三、第四阶固有频率分别为144.2 Hz、284.1 Hz、286.3 Hz、298.0 Hz,振幅分别对应为47.3 mm、102 mm、52.7 mm、49.8 mm。模态分析研究对于带式输送机滚筒的结构设计、整机性能的研究具有重要参考意义。

In order to study the natural frequency of the roller, the DSJ80/40/2 belt conveyor drive roller is taken as the research object, and the modal analysis is carried out based on the ANSYS Workbench. The first, second, third and fourth natural frequencies :144.2 Hz、284.1 Hz、286.3 Hz、298.0 Hz;amplitude corresponding to :47.3 mm、102 mm、52.7 mm、49.8 mm. respectively Modal analysis study on the structure design and integral of belt conveyor drum the study of machine performance has important reference significance.
