【Abstract】 Although the research of whole life for large electromechanical products has wide engineering background and high profits, the traditional reliability tests of the whole life often result in resource waste and environmental pollution. To make the research of reliability for this kind of system sustainable, the GM (gray model) numerical simulation and the VP (virtual prototype) physical simulation approaches aiming at small samples exploitation are introduced in this article. At the same time, an example of gearing reliability design is applied to verifying the feasibility and effectivity of the VP physical simulation method. Then using both methods alternately can be an important approach to develop small sampling complex systems.更多还原
