目前机械设计已被广大公司所认识并得以重用,但是还是有人不了解什么是机械设计。所谓机械设计就是使用技术的要求接卸工作的基本原理、结构体系等一系列的方式将每个机械每个零部件的材料,形状及尺寸以及器械保养等一些方面的设计。而且重点将器械的分析及其计算方面转化成具体的描述方法,根据这一方式进行设计。现代的很多设计方式都是根据传统的设计方式进行的操作进而融入了现代的科技成分,其目的是为了推动新只是新技术的发展。在人们的努力下已发展成了新技术由它的综合性、交叉性等特点被人们熟知。然而本文就是根据机械的特点及其设计的原则进行分析说明的并有自己的观点。 At present, mechanical design has been recognized by the majority of companies and be reused, but still some people do not understand what is mechanical design. The so-called mechanical design is the use of technology requirements of the basic principles of handling work, structural systems and a series of ways to each of the mechanical components of each material, shape and size, as well as equipment maintenance and other aspects of the design. And focus on the analysis of the instrument and its calculation into a specific description of the method, according to this approach to design. Many modern design methods are based on the traditional design methods and then into the operation of modern science and technology components, the purpose is to promote new just new technology development. Under the people’s efforts, it has developed into a new technology which is well known by its comprehensiveness and cross-cutting characteristics. However, this article is based on the characteristics of machinery and design principles to analyze and have their own point of view.
