Based on the synthetic analysis of thermal error source on gear hobbing machine, a new ICA (Independent component analysis) method is proposed in order to optimize the location of temperature sensor in this paper. A least squares modeling approach is also proposed to fulfill the thermal error modeling of gear hobbing machine. Finally, the hardware system of thermal error compensation is presented, and it is tested on Y3150 K hobbing machine. The experimental results shows that the gear machining accuracy can be improved about 2 grades through thermal error compensation, and the system is very effective.

The ever-increasing complexity of industry facilities has made the reliability analysis and assessment an imperative yet tough work. Motivated by practical engineering requirement, this paper develops a Bayesian-based information extraction and aggregation (BIEA) approach for system level reliability estimation of a complex system. It takes both subjective judgments and objective field outputs into consideration. Novel features of this approach is a unique information content based aggregation process, which allows a flexible application of this framework in separated modules on account for purpose. The coherency of which is guaranteed by the objective information content calculation. This work goes beyond the alternatives that deal with solely attributed data under ideal information circumstance, and investigates a more generic tool for real engineering application. Limitations embedded in traditional statistical modeling methods have been eliminated in a nature manner by information transition and integration. In addition, a double axis driving mechanism (DADM) for erecting the antenna of a satellite is demonstrated as case study for benefit illustration and effectiveness verification. © 2017 Beijing Institute of Aerospace Information.
