Virtual Design In The Product Design

Virtual product is the sign of key techonology in the future of the product developmentand it is the application of virtual reality yn the product development.It is based on theconcept of design process finished with the aid of computer. Based on computer simulationand lifecycle model of the product,the design, modeling, manufacture, test and analyse canbe done in the virtual enviroment.One trait of virtual product is that by using numericalmodel instead of actual product,the modeling,simulation and man-machine systemanalysis to the product can be done. The level of decision-making in the multi-goal designand the aim of global optimization and first time success can be achieved.Virtual design notonly can realize the integration between design and manufacture but also can advance therealization of distribute and corporation of product design.So it has a broad applicationforeground in the industry and has been an important way in the productdevelopment.Product modeling is a engineering technology include speciality and arts.Inthe country with developed industry, modeling has been an important factor for adding thecompetition ability. And industrial company in our country attach importance to the productmodeling and will be popularized energetically as one of the modern design methods.Thepaper studies the product modeling with the method of virtual design based on the design ofaleak testing device for oil cooler's air-proof capability experiment.The production and developemnt of the virtual design and the general situation ofvirtual reality is introduced.The relation between product development and the progress ofthe company.The aim and meaning of this paper is expounded.The traits and principle of the product modeling is analysed and modem ways forproduct modeling was introduced.Then the outlines of the whole flame of the virtualenviroment and design and its realization.The aim and requirements of evaluation for the project of the product modeling isdiscussed and then the analyse and compare of product modeling in the virtual enviromentand the simulative analyse of the product man-machine relation is introduced, at last thetraits and analyse flow of virtual modeling is expounded. The key technology of the realization of artistic modeling appearance render of thevirtual product and the analyse of the man-machine relation in the study is introduced withthe application of vtrtual design in the modeling of the product design for leak testing of oilcooler's air-proof capability experiment.At last the prospect for the paper is put forward.By the use of virtual reality technology in the product modeling,the evaluation andoptimization of the appearance and the man-roaching relation of the product can beachieved.So the course of actual test will be simple and the cycle for putting the productto the market will shortened.The competition ability of the product is improved and manyproblem in the tradional design will be resolved better.
