摘要

振动圆锥破碎机是实现超细破碎的节能型设备。振动圆锥破碎机待破碎的物料层填充在破碎机的动锥和定锥之间，利用动锥和定锥相对运动来破碎物料，同时物料层对动锥的运动也将产生反作用力。将物料层的作用简化为分段线性的接触力，将振动圆锥破碎机系统的运动简化为只考虑动锥刚体在水平面内运动，利用Lagrange方程，建立系统三自由度水平运动的模型。利用MATLAB软件，采用Runge-Kutta法对振动微分方程组进行数值计算仿真。研究了激振频率对系统动力学性能的影响。结果表明，物料层的作用使得系统刚度变大，固有频率增大；导致系统从单一频率的简谐运动变为了概周期的复杂运动。为进一步实现振动破碎机结构参数的优化奠定了基础。

Abstract

The model of vibrating cone crusher is simplified as the model of locomotory cone motion in horizontal plane. The materials layers between the locomotory cone and immovable cone will affect the motion of locomotory cone. The dynamics equations are built with the materials layers as piecewise line contract force model. Then the dynamics equations are analyzed. The result indicates the materials layers is the main source of the nonlinear system. The materials layers make the system having complex motion instead of harmonic motion with single frequency. These affect fragmentation of the vibrating cone crusher.
