【Abstract】 The life index of hydraulic components is one of the most important factors in the design of a reliable hydraulic system. To obtain the life index of a component, a series of time consuming and costly life tests is usually required. A grey prediction method for the determination of such an index under a rated condition based only on a few accelerated life test data with a relevant model for the life index developed is described. Nearly half of the time can be saved.更多还原
