【摘要】：振动筛广泛用于煤矿、石油、冶金、化工等行业,其工作效率直接影响着行业发展的进度。针对自制振动筛,在实际运用中,其主要零部件的选择和安装会存在一定的误差,主要体现在激振电机的选择、偏心装置的质量及安装角度大小、齿轮传动比的确定等,这些因素的变化对振动筛的振动效果有着很大的影响。因此,研究振动筛的动力学特性,有效选择各零部件的参数范围,增加振动稳定性,使振动筛达到正常工作的要求具有很重要的意义。本研究通过分析单轴、双轴、三轴振动筛的结构及工作原理,构建了振动筛动力学方程,基于AMESim软件建立振动筛仿真模型,在不同安装方式的条件下进行了振动筛仿真实验,详细阐述了振动筛的振动特性。利用控制变量法,基于AMESim软件,研究了单轴振动筛在不同电机转速、偏心装置质量的情况下,振动筛的振动方向、振幅大小、角速度变化;研究了双轴振动筛在改变电机转速、偏心装置质量、偏心装置安装角度时,振动方向角及激振力形状变化;研究了三轴振动筛在不同电机转速、齿轮传动比、偏心块安装角度下的振动筛振动效果;同时,基于AMESim与ADAMS软件,对单轴振动筛进行联合仿真,研究了在不同电机转速、偏心质量、筛面倾角的条件下振动筛的振动轨迹、角速度、振幅、抛掷指数的变化。
[Abstract]:The vibrating screen is widely used in coal mine, petroleum, metallurgy, chemical industry and so on. Its working efficiency directly affects the progress of the development of the industry. In view of the self-made vibrating screen, there will be certain errors in the selection and installation of its main parts and components in practical application. It is mainly reflected in the selection of exciting motor, the quality and installation angle of eccentric device, the determination of gear transmission ratio and so on. The change of these factors has great influence on the vibration effect of vibrating screen. Therefore, the dynamic characteristics of vibrating screen are studied. It is very important to select the parameter range of each component effectively, increase the vibration stability, and make the vibrating screen meet the requirement of normal operation. This study analyzes the structure and working principle of single axis, double axis and three axis vibrating screen. The dynamic equation of vibrating screen is constructed, the simulation model of vibrating screen is established based on AMESim software, the simulation experiment of vibrating screen is carried out under the condition of different installation mode, the vibration characteristic of vibrating screen is expounded in detail, the control variable method is used, and the simulation model is based on AMESim software. The changes of vibration direction, amplitude and angular velocity of single shaft vibrating screen under different motor speed and eccentric device quality are studied, and the change of motor speed and eccentricity device quality is studied. The vibration direction angle and exciting force shape of the three-axis vibrating screen under different motor speed, gear transmission ratio, eccentric block installation angle are studied. At the same time, based on AMESim and ADAMS software, the vibration direction angle and exciting force shape change are studied. In this paper, the vibration track, angular velocity, amplitude and throwing index of the vibrating screen are studied under the conditions of different motor speed, eccentricity mass and inclined angle of the screen.
