【摘要】：基于某型号变椭圆轨迹振动筛,分析了变椭圆轨迹振动筛的工作原理,编写了Matlab计算程序,对于原始设计参数进行了运动学仿真,包括运动轨迹、抛掷指数、椭圆长轴倾角等;进一步分析了相位差角、激振力、激振器安装位置等设计因素对运动轨迹参数的影响,重点分析了椭圆长轴倾角及抛掷指数的变化规律;对该振动筛提出了激振器合理选择及安装位置的建议,并进行了计算机仿真。结果表明,改进后的振动筛振动轨迹及运动参数更加符合设计要求。文章的研究方法及计算结果可对实际振动筛的设计提供一定借鉴和参考。
[Abstract]:Based on a certain type of variable elliptic trajectory vibrating screen, the working principle of the variable elliptic trajectory vibrating screen is analyzed, and the Matlab calculation program is compiled. The kinematics simulation of the original design parameters is carried out, including the motion trajectory, throwing index, obliquity of the long axis of the ellipse, etc. The influence of the design factors such as phase difference angle, exciting force and the installation position of exciter on the motion track parameters is further analyzed, and the variation law of the obliquity of the elliptical long axis and the throwing index are emphatically analyzed. The reasonable selection and installation position of the vibrator are put forward, and the computer simulation is carried out. The results show that the vibration trajectory and motion parameters of the improved vibrating screen are more in line with the design requirements. The research method and calculation results can be used for reference in the design of actual vibrating screen.
