Multiple physical signals based residual life prediction model of slewing …

Because slewing bearing is a large low-speed heavy-load bearing, vibration signal is insufficient. On the other hand, because of the influence of the environment, it is difficult to obtain failure data of slewing bearing under actual working conditions, and tests also will entails high costs, so that the failure data is limit.
