基于UG的花生收获机机械CAD图纸设计.doc

摘要 虚拟设计是近年来随着计算机辅助设计(CAD)技术和虚拟现实(VR)技术相互结合而发展起来的一种新兴设计技术。与传统的设计方法相比,虚拟设计开发周期短,可以及时有效地发现和解决设计中存在的问题,提高了设计的质量和效率。目前, UG、Pro/E等大型CAD/CAE/CAM集成化软件可以很好地实现机械产品的虚拟设计。 Unigraphios(简称UG)是当前世界上最先进和紧密集成的、面向制造行业CADC/AMC/AE高端软件。UG软件集成了全面产品工程解决方案，使得用户能够数字化地创建和获取三维产品定义，可以用来从事概念设计、工业设计、详细的机械设计以及工程仿真和数字化的制造等领域。 UG是美国UGS公司开发的三维参数化软件,是当前最为先进的面向制造业的计算机辅助设计、分析和制造高端软件之一。UG不仅具有强大的实体造型、曲面造型、虚拟装配和工程图设计等软件,而且在设计过程中可进行有限元分析和机构运动分析,提高了产品设计的可靠性。同时,可用建立的三维模型直接生成数控代码,用于数控机床加工。另外,还提供了UG/OPEN GRIP和UG/OPEN API等开发模块,便于用户开发符合自己要求的专用系统。UG以其强大的功能而广泛应用于航空航天、造船、汽车、机械等领域。 A peanuts harvester includes a truck body, plant row dividers, stalk straighteners, peanut diggers, a plant feeder, a tilted conveyer, a horizontal conveyer, a peanut stripper and a peanut collector such that the dug peanut plants are conveyed to the horizontal conveyer where the upper stalks are held by the conveyer and the lower peanuts on roots are stripped by the peanut stripper, whereby the stripped peanuts are screened, cleaned and collected into bags for efficient integrated harvesting of peanuts. 关键词 虚拟;设计; UG; 软件 Abstract Supposing design is that a kind of in recent years, being tied in wedlock mutually but developing with the computer-aid design (CAD) technology and the suppositional real (VR) technology designs a technology. Compared with the tradition design procedures, have supposed the fault designing a construction cycle , can discover and resolve have problem designing middle in time effectively , have raised mass and efficiency designing that. At present, UG , Pro/E wait for large-scale CAD/CAE/CAM to integration-rization the software can realize suppositional machinery product design very good. Unigraphios (be called UG for short) is current advanced and rapid and intense in the world integrations , is geared to the needs of the high-end fabrication industry CADC/AMC/AE software. The integrated all-round UG software product project is resolved scheme, the feasible consumer is able to establish and gain thr
