发布时间:2018-09-09 19:29
【摘要】:应用PROE软件建立了单边驱动式摇摆筛的三维结构模型,并对其进行动态仿真分析,得到作用在偏心轴上的载荷历程。运用解析法和有限元法对偏心轴应力进行分析,得到其应力分布曲线和应力云图,分析结果表明,偏心轴上的危险部位出现在中间轴承座支撑处,最大应力值为35 MPa。运用局部应力应变法对偏心轴疲劳寿命进行分析,得到单边驱动式摇摆筛偏心轴的疲劳寿命为0.98a,通过分析能够有效预防事故的发生。该研究成果为偏心轴的设计和改进提供了可靠依据。
[Abstract]:The three-dimensional structure model of one-sided drive rocking screen is established by using PROE software, and the dynamic simulation analysis is carried out, and the load history on the eccentric shaft is obtained. The stress distribution curve and stress cloud diagram of eccentric shaft are obtained by using analytical method and finite element method. The results show that the dangerous part of eccentric shaft appears at the support of the middle bearing seat, and the maximum stress value is 35 MPa.. The fatigue life of eccentric shaft is analyzed by using local stress-strain method, and the fatigue life of eccentric shaft of single drive rocking screen is 0.98 a, which can effectively prevent the occurrence of accident. The research results provide a reliable basis for the design and improvement of eccentric shaft.
