振动试验台的设计及其动态特性分析

Design and Dynamic Characteristic Analysis of Vibration Testing Bed

文中借助于SolidWorks软件设计了一款振动试验台,并用ANSYS软件分别对振动试验台的固定台和不同工况下的支架做了模态分析,得到固定台和支架的前几阶固有频率及对应振型,找出其结构的薄弱点,为振动试验台的进一步结构优化和动力修改提供了数据。

This paper designs the vibration testing bed using SolidWorks. The modality analysis of support frame works under different conditions and the fixed table of the vibration testing bed are carried out using ANSYS respectively. And the first fewer ordersx natural frequency and corresponding vibration models of the support frame and the fixed table are obtained to provide the data support for the further structure optimization and dynamic modification of the vibration testing bed .
