中文摘要：为了分析碟式分离机的转鼓体应力分布的情况,课题组应用ANSYS有限元分析法建立了转鼓的分析模型。锁环螺纹联接、转鼓内装件都会对转鼓体应力分布及大小产生直接影响,因此,对包含内装件的真实转鼓进行了建模仿真分析。探讨了薄厚碟片组对转鼓体应力场与位移场的影响,并利用光学法数字图像相关(DIC)非接触测量仪器及专用软件,对空载转鼓体外圆壁面的位移场分布进行了实测。研究结果表明:该碟式分离机转鼓体的应变(位移)场的仿真分析结果与实测结果的位移场分布规律相近;转鼓体内侧底部处的应力负荷最大处位于靠近碟片架内侧处;依据实测数据有待对有限元分析模型的建模方法做进一步的改进。研究结果对碟式分离机转鼓的结构优化、复杂组合结构的转鼓总成的有限元建模具有直接的参考作用。

外文摘要：In order to analyze the strain distribution of the bowl body in disc separator,a finite element analysis(FEA)simulation model of the bowl was established by using ANSYS finite element analysis technology.The threaded connection of the lock ring and the bowl fittings were in effect on the strain distribution and the size of the bowl body.Therefore,simulation analysis was carried on and the influence of thin and thick disc group on the strain and displacement field of the bowl body was discussed.By means of optical non-contacting measurement instrument digital image correlation(DIC),the displacement field distribution of the bowl body outside the round wall was measured.The results show that the displacement field distribution stimulation results of the bowl body of the disc separator is similar to that of the measured results.The maximum strain load is located near the inner side of the disc frame at the bottom of the bowl body.According to the measured data,the modeling method of finite element analysis model needs the further improvement and optimization.
