带清洗烘干装置的秸秆粉碎机设计 摘要 锤片式粉碎机是饲料加工机械的四大主机之一,是饲料生产必要的设备之一,其性能对饲料厂的节能降耗意义重大。分析了锤片式粉碎机的结构特点,设计出满足要求的锤片式粉碎机。建立了锤片式粉碎机转子的离散化模型，利用ADAMS软件术对锤片对称交错排列形式的粉碎机转子进行动力学仿真分析，得到了与实际情况相近的结论。仿真结果表明，锤片对称交错排列转子的平衡性较好，其中交错排列转子两端轴承承载情况相近,转子稳定性好。转子是锤片式粉碎机的主要工作部件。利用Pro/E对锤片式粉碎机转子中的各零件进行三维建模、虚拟装配、模型分析和动态仿真。设计者可以充分利用Pro/E单一数据库管理技术，通过改变尺寸参数来方便地修改和更新零件，还可以直观地观察和分析转子的外形、零件间的相互位置关系和运动状态。 关键词：振动；仿真；锤片式粉碎机； Pro/E；转子；三维建模 Abstract Hammers mill, which is one of the four main feed processing machineries and one of the necessary equipment of feed processing, has a great influence on economy energy sources in feed factory. In this paper the structural features of the hammers mill are analyzed. The statics and the vibration characteristic of its frame are investigated with the ADAMS software. A discrete model of hammers mills rotor was set up. Mills rotor arranged in different hammer forms was analyzed by way of dynamic simulation with virtual prototype technology. The result that is similar to facts was deduced. The conclusion indicated that the rotor with interlaced or symmetry-interlaced hammer form has better balance and the former is with good stability because of its equal load on each bearing. Rotor is an important assembly of hammers mill. This research utilized Pro/E to carry out three-dimensional modeling of the parts of hammer mill’s rotor, virtual assemble, model analysis, and motion emulation. Designers can modify the parts easily by changing size parameters, and also can observe forming, position relation of parts and motion state of the rotor.
