|
摘要
为研究振动试验台的振动特性,检验试验台设计的合理性,利用ANSYS软件对振动试验台进行了模态分析,得到了振动试验台的固有频率,在此基础上进行了该结构的谐响应分析,得到了在预定频段下施加载荷位置处的位移响应。根据分析结果确定了振动试验台的结构优化思路,并对振动试验台的结构进行简单优化,优化之后经进一步分析达到了设计要求。
In order to study the vibration characteristics of the vibration test bench and check the rationality of the design of the test bench,the modal analysis of the vibration test bench is carried out by using ANSYS software,and the natural frequency of the vibration test bench is obtained.On this basis,the harmonic response analysis of the structure is further conducted,and the displacement of the loading position in the predetermined frequency band is obtained.According to the analysis results,the structure optimization ideas of the vibration test bench is determined,and the simple structure optimization of the vibration test bench is carried out,and the optimized structure can meet the design requirements.
