建立了五自由度三轴椭圆振动筛系统动力学模型,借助MATLAB进行了数值仿真分析。仿真结果表明:振动筛筛箱的运动轨迹为椭圆,从进料口到出料口,长短轴之比逐渐减小,方向角逐渐增大;探讨了隔振架质量、隔振弹簧刚度等因素对系统动态响应的影响,针对三轴椭圆振动筛的建模、设计和使用提出了具有指导性的建议。 A five-DOF three-axis elliptical vibrating screen system dynamics model was established, and numerical simulation analysis was carried out with MATLAB. The simulation results show that the moving path of the shaker screen box is elliptical, the ratio of the long axis to the short axis decreases gradually and the direction angle increases gradually from the inlet to the discharge port. The factors such as the quality of the vibration isolator and the stiffness of the vibration isolating spring are discussed The impact of the system on the dynamic response, for the three-axis elliptical shale shaker modeling, design and use of recommendations made with guidance.
