摘 要
电机(英文:Electric machinery,俗称“马达”)是指依据电磁感应定律实现电能转换或传递的一种电磁装置。在电路中用字母M(旧标准用D)表示。它的主要作用是产生驱动转矩,作为用电器或各种机械的动力源。发电机在电路中用字母G表示。它的主要作用是利用机械能转化为电能,目前最常用的是,利用热能、水能等推动发电机转子来发电。电气工作者把分布参数系统问题归结为集中参数系统问题求解是屡见不鲜的。有限元数值解法就是这种相同的思考方法。但是有限元问世后在电工行业中却远不及力学领域等应用得充分。 有限元法的特点是适用于求解各种形式几何上、物理上复杂的问题精度高通用性强对问题的处理既彻底又系统适用于采用电子计算机方式。它本是线性问题的解法但通过迭代法如牛顿-拉裴森迭代法也能巧妙地解决非线性问题。用来求解电磁场问题远较电工行业中常用的图解法、电解槽法等优越。因此随着科学技术的发展各类超高压、大容量、高精度的电工产品的研制其磁场等的精确计算直接关系到该产品的优异性能和技术经济指标。有限元法这一有力工具在电工行业中在电磁研究领域里越来越有广泛的应用。 用有限元法对异步电动机性能进行分析的方法在实际电机产品中得到验证。在磁场中向量场函数B的旋度
Abstract
The development direction of harvester will be to high-tech direction, making out the applicability of harvester is the development of the market, is very promising for different regions developed different harvester. Thus, the corresponding manufacturing combine high performance is the development of foreign harvester. The rice combine harvester can complete harvesting, threshing, separation and bagging operations at one time. The machine has the advantages of small volume, The development direction of harvester will be to high-tech direction, making out the applicability of harvester is the development of the market, is very promising for different regions developed different harvester.
