摘要
本文通过建立摆锤式自动平衡装置的数学模型,针对摆锤位置对摆锤式自动平衡装置的影响编制了相应的程序流程图,并据此进行了基于MATLAB数值仿真,得出如下结论:摆锤装在转盘中心时,摆锤可以绕旋转轴大幅摆动,摆锤式自动平衡装置同球式自动平衡装置一样,具有完全减振的能力;无滚动摩擦力时,摆锤可以停留在理想平衡位置完全平衡偏心质量,具有完全减振能力;有滚动摩擦力时,系统有微小的残留振幅,摆锤不安装在转盘中心时,随摆锤旋转中心到转盘中心距离的增加减振效果随之缓慢减小,此种情况下摆锤安装位置对系统减振性能影响不大。
Through establishing the math mode of pendulum-type automatic balancer, the procedure flow chart is made according the efffect of pendulum positon on pendulum-type automatic balancer. The following are concluded by simulation on MATLAB figure：While fixed on the center of rotary, the pendulum can swing around the rotation axis, and pendulum-type automatic balancer can fully remove vibration as the global-type automatic blancer;without rolling friction, the pendulum can stay at the ideal banlance point to make the eccentricity quality in balance, fully removing vibration;with rolling friction, a little vibration left exists in the system, and while the pendulum is not fixed on the center of rotary, the effect of vibration reduction minishes as the distance between pendulum rotation center and rotary center increases, where the fix position of pendulum hardly influences the ability of system vibration reduction.
