摘要

惯性圆锥破碎机的物料作用及其惯性力等交变载荷会引起机壳、主轴等构件的耦合振动，影响破碎机性能与寿命。应用反相双激原理，设计了一种具有完全动平衡并能提供更大破碎力的新型惯性圆锥破碎机；基于多体动力学与离散元耦合模型，提出了反相双激振器破碎机动力学仿真及试验验证的系统分析方法。通过仿真分析与样机试验，验证了耦合模型的有效性及该新型破碎机具有更好减振和破碎力增益效果。研究了定锥质量和动锥等激振机构质量对整机振动和破碎力的影响，其结果表明：该反相动平衡惯性圆锥破碎机能使定锥减重59%且动锥等激振机构减重24%。

Abstract

The rock and inertia force of inertia cone crusher can cause coupling vibration of shell, spindle and other components and affect the performance and service life of the crusher. A new type of inertia cone crusher with complete dynamic balance and greater crushing force is designed based on the inverse double excitation principle. Based on the coupled model of multi-body dynamics and discrete element method, a system analysis method of the dynamic balance crusher dynamics simulation and tested verification is proposed. The comparison between simulation analysis and prototype test shows that the coupling model is effective and the new crusher has better vibration reduction and crushing force gain effect. The influence of the mass of the fixed cone and the moving cone on the vibration and crushing force is studied. The results show that the inverse dynamic balance inertia cone crusher can reduce the weight of fixed cone by 59% and that of vibration mechanism such as dynamic cone by 24%.
Key words: inertia cone crusher; inverse dynamic balance; multi-body dynamic; discrete element method; prototype test
