【摘要】 手套漏气检测装置是手套漏气检测设备的核心所在,其稳定性对手套漏气检测精度有着重要的影响。为了降低手套漏气检测装置的变形和振动对手套漏气检测精度的影响,以手套漏气检测装置的支架为研究对象,运用SolidWorks对检测支架进行三维模型绘制且保存为parasolid格式导入到ANSYS Workbench中进行分析,得到检测支架形变量为0.009mm,变形量非常小,对检测精度造成的影响可以由PLC内部程序设置的修正值予以消除。再对检测支架进行模态分析和谐响应分析,得到前六阶固有频率、振型以及振幅与频率的关系,通过对比模态分析与谐响应分析结果,发现三阶固有频率186.43Hz对检测支架影响较大,容易引起共振现象。更多还原

【Abstract】 Glove air leakage detection device is the core of glove air leakage detection equipment,and its stability has an important impact on glove air leakage detection accuracy.In order to reduce the deformation of glove air leakage detection device and the influence of vibration on glove air leakage detection accuracy,this paper takes the bracket of glove air leakage detection device as the research object,draws the three-dimensional model of the detection bracket by SolidWorks,saves it in parasolid format,and imports it into ANSYS Workbench for analysis.The deformation of the detection bracket is 0.009mm,and the deformation is very small.The influence on detection accuracy can be eliminated by the correction value set by PLC internal program,and then modal analysis and harmonic response analysis are carried out on the detection bracket.The first six natural frequencies,vibration modes and the relationship between amplitude and frequency of the detection bracket are obtained through modal analysis and harmonic response analysis.By comparing the results of modal analysis and harmonic response analysis,it is found that the third natural frequency 186.43Hz has great influence on the detection bracket,which is easy to cause resonance phenomenon.更多还原
