With today's highly reliable components, we are often unable to obtain a reasonable amount of test data under normal use condition. For this reason, accelerated tests method is the reasonable procedure to be applied. It is used to determine the reliability of a product in a short period of time by accelerating the use environment. Application of the method of accelerated tests can save cost that we used to pay for overcoming the dilemma of not being able to estimate failure rates by testing directly at use conditions. In the method of accelerated tests, acceleration factor is known or there exists a mathematical model which specifies the relationship between lifetime and reliability or failure. This model proves its value not only as a way of a validation model for classical reliability models existing in the literature, but more, as a quantifier of reliability gain resulting when replacing or modifying parts (cost-benefit analysis).
In recent years many developments have been made in the area of the vibration behavior of the supported by bearings or journal bearings rotating shafts. The results, if they are generally acceptable for common-use in terms of operating conditions, are far from meeting the aircraft industry, where the machining at high speeds is an undeniable need. This research therefore is aimed to provide an analytical simulation based on theoretical developments of the vibration response of a ball bearing. The generation of vibration by a point in a rolling element bearing is modeled as a function of the rotation of the bearing, the distribution of the load in the bearing, the transfer function between the bearing, transducer and elasticity of the bearing structure. The essence of this work is to present an analytical model of a specific type single of row effect balls (SKF 6004). This study is a first step dedicated to define the geometric characteristics, and in second time to determine the equations governing the distribution of responsibilities within the ball bearing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
