文档介绍：管磨机动态特性及系统的测试分析
摘要:磨机是发电、选矿、化工和建材等重工业领域中最广泛采用的粉磨机械,其主要机件有传动装置、支承装置、回转筒体。本文建立了边缘传动式磨机系统的“小齿轮——传动轴——减速机大齿轮”横向振动的模型,分析计算了系统横向振动的动态特性,对系统的载荷进行了测试分析,同时,还建立了磨机系统的扭转振动模型,利用递推计算法对系统进行了扭转振动动态特性分析,验证了递推计算法的通用性。最后,×13m的磨机系统进行了动态特性的实例分析。研究边缘传动磨机系统的动态特性,对避免由于激励频率接近或等于系统的固有频率而导致共振及设备的失效,预测系统在可能激励下的响应特性,优化系统结构等等都具有很重要的意义。用传递矩阵法及通用计算程序可以简便地分析边缘传动磨机系统横向振动的固有特性,以及计算不同激励情况下系统的响应,为研究边缘传动磨机系统横向振动的动态特性提供了一个方便有效的方法。边缘传动磨机系统是一个模态偶合较紧的系统,因此,在磨机系统的设计、运行中,应注意使激励频率避开系统的固有频率,以免发生设备的早期失效。边缘传动式磨机系统的传动轴的设计是合理的。系统阻尼对系统的动态特性影响很大,是系统的一个重要性能参数。边缘传动磨机系统,可以通过实测低速轴的扭矩来确定系统中减速机的负载状况。

Tube Mill and testing of the system Dynamic Analysis
Abstract:Tube Mill is important rules that Research for Dynamic characteristics of the mill system of single -pinion drives in operation to prevent damage from the resonance between fix frequency and bestir frequency In this paper , the pattern of Pinion---Drive shaft---Decelerator gear vertical vibration in the mill system of single -pinion drives is established . Dynamic characteristics of vertical vibration is analyzed and calculated ,and its excitation loads are tested Simultaneously , the model of torsion vibration in system is also established, its dynamic characteristics is analyzed by using recurrence calculus method , thus , this methods current is verified . Finally, the paper studied the dynamic characteristics of mill system. Mill system of single - pinion drives is lighten, so the design and run of mill system, bestir frequency must avoid design of drive shaft is rational in mill system of single - pinion drives. It is very large that damp of system effect to dynamic characteristics, so the damp is a important parameter. Load of gear box can be decided by measuring of low speed shaft contort. In mill system of single - pinion drives.
