Example Sentences:

	1.	Convex - concave shape : unique designed of convex - concave shape , which can strengthen and expand the heated measure . promote to absorb the light and heat energy . increase the radiating energy 在省油器表面形成许多凹凸面：使表面受热面积加大，促进吸收光能及热能，增加红外线放射能量。
	2.	As a new type gear transmission , double circular arc profile bevel gearing carries out its transmission by means of meshing between convex - concave tooth profile in both of the direction of tooth trace and the direction of tooth depth , so it has advantage of high load capacity , long service life , easy forming hydrodynamic oil film between teeth as well as high quality of running - in etc . therefore , more attention has been paid to its application and research in recent years 作为一种新型齿轮传动方式，双圆弧弧齿锥齿轮传动不论在齿线方向、还是在齿高方向，均为凸、凹齿廓相啮合，因而它比一般的弧齿锥齿轮传动的承载能力高，使用寿命长；并且在啮合过程中两齿面间容易形成润滑油膜，具有良好的跑合性能，所以对它的应用和研究日益受到人们的重视。
	3.	This paper referred to the massive domestic and foreign technical material , elaborated in the sheet forming value simulation theory essential technology in detail , points out when analysis sheet forming question should use the big distortion ball plasticity fem and introduce the application characteristic and the function summarizes of the sheet forming simulation software dynaform . secondly , analyzed the cover forming characteristic , simultaneously introduced the influence cover forming factor in detail : such as ramming direction , the craft addendum surface and the material pressing surface , the radius of convex - concave mold , draw bead , pressure strength , blank size and craft margin and so on . and simulates many typical automobiles cover panel with software : such lateral board , back taillight pedestal and storage cover 其次,分析了覆盖件成形的特点和要求,同时详细介绍了影响覆盖件成形的因素如冲压方向、工艺补充面和压料面、凸凹模圆角、拉延筋、压边力、坯料尺寸和工艺切口等,并用数值模拟软件对多个典型的汽车覆盖件汽车后侧围板、后灯座以及轿车后备箱盖的冲压成形情况进行模拟,用模拟结果优化拉延工艺方案,比较了内覆盖件和外覆盖件在成形特点和要求的一些异同点,以及常见的起皱、拉裂和回弹、成形不足等缺陷的产生机理和相应对策,重点介绍工艺补充面和压料面的设计及优化方法,因为拉延是冲压工艺的关键工序,而工艺补充面和压料面的设计是拉延工序的关键,对消除缺陷至关重要。
