In this paper, a dynamically-weighted software reliability combination model is proposed, aiming at improving predictive quality. The process of forming the combination model includes selection of component models and determination of weight assignment. Criteria for selecting component models include life cycle phase, trend exhibited by failure data, validity of model assumptions and predictive biases...
Because of the advantage of gear, gearbox was used widely. But its fault also brought many losses of the production and society. It was necessary to research and analysis on the dynamical behavior of the gear system. One kind of gear fault was numerically simulated so that the influence of gear fault to change of vibration state was studied theoretically, and the symptom generated by faults was found...
