For estimating the lower confidence limit of system reliability, Viltual System Method greatly improves the Lindstrom and Maddens method with such advantages as level consistency and asymptotic ef- ficiency. In this paper, the generalized Virtual System Method is employed to estimate the parameter of any subsystem based on the data collected from the system. It is shown that the proposed estimator is asymtotically efficient and the constructed estimate for the lower confidence limit of the parameter is not only asymptotically efficient but also level consistent.
RESEARCH OF THE REGENERATIVE CHATTER CONSIDERING THE EFFECTS OF THE PARAMETERS OF THE CUTTING TOOL SUBSYSTEM AND THE WORKPIECE SUBSYSTEM SIMULTANEOUSLY
According to the design requirements, the design method of the parameters of the system is provided and the parameters and measuring average of the whole system are also calculated.
This paper builds the model of single axis servo system, and analyzes the different influence of each subsystem's parameters to the system performance.
