Abstract
Keywords: developments, prototype, test, analyses, economy.
The paper presents aspects concerning the using of technical modern elements in the virtual prototyping end experimental results on the physical models .The virtual prototyping is a process which uses a virtual prototype in place of physical prototype for the testing and the evaluation of specific features of designed product. The virtual prototype is created by computer such as it could assign the specific features as close as possible to the real conditions which permit its function simulation in the conditions for which is designed. The virtual prototyping permits the replacing of efficiency classical design process in the increased conditions. Based on virtual prototype is made real prototype that is used for testing.
