Rapid prototyping (RP) is the production of a physical model from a computer model without the need for any jig or fixture
or numerically controlled (NC) programming. This technology has also been referred to as layer manufacturing, material deposit
manufacturing, material addition manufacturing, solid freeform manufacturing and three-dimensional printing. In the last decade,
a number of RP techniques has been developed. These techniques use different approaches or materials in producing prototypes
and they give varying shrinkage, surface finish and accuracy.
Virtual prototyping (VP) is the analysis and simulation carried out on a fully developed computer model, therefore performing
the same tests as those on the physical prototypes. It is also sometimes referred to as computer-aided engineering (CAE) or
engineering analysis simulation.
This paper describes a comparative study of the two prototyping technologies with respect to their relevance in product design
and manufacture. The study investigates the suitability and effectiveness of both technologies in the various aspects of prototyping,
which is part and parcel of an overall design and manufacturing cycle. 相似文献

Medical imaging has been used to provide information for diagnostic and therapeutic purposes. The use of physical models provides
added values in these applications. Rapid prototyping (RP) techniques have long been employed to build complex 3D models in
medicine. However, publications regarding the dental application of RP technologies are still rare. This paper reviews and
discusses the basics and applications of RP techniques in dentistry: (1) construction of a computer aided design (CAD) model,
including data acquisition, data processing, and the corresponding machines and CAD packages, (2) typical RP systems and how
to choose them, and (3) current and potential use of RP techniques in dentistry. Practical application examples of RP techniques
in dentistry are provided. 相似文献

首先,采用自制的简易三坐标测量仪对样车的各铰点(硬点)进行实测,并通过实测或辨识方法确定减振器、转向系统等部分的特征参数;然后,在多体动力学软件中建立该样车整车虚拟样机模型,并建立基于横摆和侧偏的车身稳定性控制系统模糊控制器,其仿真结果表明所建控制器控制效果良好。最后,为了探析样车原装稳定性控制系统控制算法等,对样车进行了冬季试验,并得出了一些有益的启示,这为下阶段自主开发汽车稳定控制系统提供了参考。 相似文献
