摘要
基于Lagrange法建立振动筛系统动力学模型,并求解其响应.利用多体动力学软件对直线振动筛进行运动仿真分析,求出振动筛在激振力作用下的振动位移、速度、加速度及动画直观显示振动筛的运动情况.在此基础上,根据运动学分析载荷,建立振动筛的有限元分析模型并进行静力学和疲劳分析.该方法实现了运动分析、强度分析、疲劳分析的结合,为开发高可靠性、高性能的大型振动筛提供了依据.
Based on Lagrange methods, the dynamic model of linear vibrating screen system is established to work out its response. Using multi-body dynamics software to do motion animation analysis in order to obtain the vibrating displacement, velocity and acceleration, and then to animatedly display the motion of the Vibrating Screen. The FEA model is therefore established for static and fatigue analysis by means of kinematical analyzing load. This method successfuly combines dynamic analysis with stress analysis and fatigue analysis and effectively provides foundation, for developing large-scaled vibrating screen with high reliability and performance.
