无料钟炼铁高炉布料榴槽传动系统运动仿真及故障诊断（本科毕业论文设计）.doc

摘 要
炉顶旋转布料溜槽传动齿轮箱是大型炼铁高炉极为重要的部件，它的运行状况直接关系到高炉炼铁生产的安全、正常进行。尽管该设备部件在设计时考虑得比较细致、周全，使用单位还不断加大检修力度，但是在使用过程中仍然难免发生意外故障甚至严重事故。生产实践表明，有必要对旋转溜槽传动齿轮箱进行运动故障仿真，对生产过程中会发生的故障进行诊断，防患于未然，并给维修提供正确的信息，提高经济效益。
本文通过分析高炉布料齿轮箱的结构特点和传动关系，研究了布料溜槽在转动而不倾动、倾动而不转动、同时转动和倾动等情况下的运动特性。利用ADAMS软件建立了布料溜槽传动系统的虚拟样机模型，在虚拟样机基础上进行了各种传动形式的运动学仿真。根据布料溜槽运动特征及驱动电机的动力特征分析了在各种条件下的运动征兆，为故障点的评判与确定提供依据，再结合机组的运行工况、历史资料及专家的经验知识对故障发生的部位做出准确判断，以缩短维修时间。

ABSTRACT
The transmission gearbox of distributor chute on BF top is a key equipment of iron plant.It’s condition concern the normal production of iron-smelting directly .Although the design of the equipments is very careful and the overhaul is getting stronger ,the accidental fault is still unavoidable. The production practices is showing that It is essential for gearbox to Fault simulation campaign. By analysing the signal , We can prevent trouble before it happened and change maintaining regularly into foreseeing maintaining.
This article through the analysis blast furnace cotton material gear box's unique feature and the transmission relations, has studied the cotton material chute, in rotation, but not preferential motion, preferential motion but does not rotate, simultaneously rotates and situation and so on in preferential motion cotton material characteristics. Has established the cotton material chute transmission system's dummy specimen model using the ADAMS software, has carried on each transmission form kinematics simulation in the dummy specimen foundation. And actuated electrical machinery's dynamic characteristic according to the cotton material chute movement characteristic to analyze under each kind of condition movement indication, provided the basis for the fault point judgment and the determination, the recombination unit's operating condition, the historic information and the domain expert's experience knowledge the spot which occurred to the breakdown makes the accurate judgment

Key words：Gearbox ，Fault diagnosis ，ADAMS , Simulation
