【摘要】 当今世界能源问题日趋紧张,环境问题一再恶化。可以利用燃料电池来解决这两个问题,锌空燃料电池在许多方面具有很大的优势:锌空燃料电池的比能量最高,负极活性物质为锌,其贮存量大,来源广泛,价格相对低廉,且性能稳定。本文是从锌空燃料电池极片的成形方法上进行研究的,设计的成形机械模型采用了新的成形方法——干嵌法,这种方法在成形质量、节省能源方面有很大的优势。本文对锌空燃料电池的制备工艺进行了分析,把其分为几大模块,各个模块在结构上是相对独立的,但是在极片的成形过程中,他们之间又有很强的耦合性。并且还对其中的模块进行了三维建模。本文找到了一种有效的测量轧制压力的方法——应变片测量法,详细阐述了轧制力测试技术理论,探讨了在极片的轧制过程中轧制压力实测、工程计算方法和影响轧制单位压力的因素。该方法在理论上是非常有效的,可用于实际测量。本文还通过利用Pro/ENGINEER软件对模型进行了三维建模,并利用Pro/ENGINEER软件中的运动仿真模块对模型的关键部分进行了干涉检验,从而避免了在制造物理样机的时候出现不必要的麻烦。同时利用Pro/MECHANICA软件对轧机进行了有限元分析和位移变形分析,得到了轧辊的应力情况和变形程度,同时对轧辊轴作了优化分析,通过优化分析减小了轴的质量、应力和变形,大大提高了极片的成形质量。
【Abstract】 Nowadays, energy problem is gradually nervous in the world and the environment problem worsens again and again. We can make use of the fuel-cell to resolve these two problems, the zinc-air battery have big advantage in many respects: The zinc-air battery have the most comparable energy, the anode active material is zinc which have great stores capacity, the source is extensive, the price is opposite cheap, and the function is stable.This paper is study on the molding method of the electrode slice of zinc-air battery, the shaping machine model which we design is use of a new method—dry-embedded method, this method has many advantage in the aspects of taking shape quality and save energy. This text analyse on the manufacture technics of the electrode slice of zinc-air battery, which is divided into several molds, each mold is independent on the structure, but in the shaping process of the electrode slice, they have very strong coupling character. And as to its 3D has been set up.This text still found out a kind of valid method to measure rolling pressure—the slice of strain method, elaborated the technique theories of testing, and inquiried into the rolling pressure testing, engineering calculational methods and the factors of influence the rolling unit pressure in the shaping process of the electrode slice. This method is very valid in theoretical, can used in actual testing.This text make use of Pro/ENGINEER to set up its 3D model, and made use of structure module and motion moudule to analyse key part in interference, thus avoided unnecessary trouble at the time of making physical machine. Made use of Pro/MECHANICA to carry on finite element analysis and analysis the displacement of rolling machine in the meantime, we have got the stress of roller and its displacement, structure optimization analysis have been used in roller, via structure optimization analysis we minished the weight, stress and displacement of axes, the quality of electrode slice has been consumedly raised.
