HSFDONES: A Self-Leaning Ontology-Based Fault Diagnosis Expert System Framework
No full textInternational audienceHSFDONES is an expert system fault diagnosis which makes the fault diagnosis working more intelligently, HSFDONES uses the ontology-based self-leaning theory and technology to build fault diagnosis expert system. The fault diagnosis knowledge structure is defined and the relevant structure ontology and core fault ontology is researched in HSFDONES; the fault diagnosis data warehouse is built, the decision tree and Apriori algorithm are used to acquire fault knowledge to realize HSFDONES’s ontology self-learning. HSFDONES offers system framework for building intelligent fault diagnosis system. Finally the agricultural machinery’s hydraulic fault diagnosis expert system was developed on the basis of the framework

No full textImprovement of the magnetic property, thermal stability and corrosion resistance of the sintered Nd-Fe-B magnets with Dy80Al20 addition
No full textTo improve the coercivity and thermal stability of the Nd-Fe-B sintered magnets simultaneously, the Dy80Al20 (at%) powders with low melting point were introduced into the Nd-Fe-B magnets. Additionally, the magnetic properties, microstructure and thermal stability of the sintered magnets with different amounts of Dy80Al20 were investigated. By adding a small amount of Dy80Al20, the coercivity was significantly increased from 12.72 to 21.75 kOe. As indicated by the microstructure analysis, a well-developed core-shell structure was formed in the magnets with the addition of Dy80Al20. The improvement of magnetic properties could be attributed to the refined and uniform matrix phase, continuous grain boundaries and a (Nd, Dy)(2)Fe14B hardening shell surrounding the matrix phase grains. With the addition of 0-4 wt% Dy80Al20 powder, the reversible temperature coefficients of remanence (alpha) and coercivity (beta) of the magnets could be improved from -0.117 to -0.108%/ degrees C and -0.74 to -0.66%/ degrees C in the range of 20-100 degrees C, respectively. Additionally, the irreversible loss of magnetic flux (hirr) decreased sharply as Dy80Al20 powder was added. The results of temperaturedependent magnetic properties suggest that, the thermal stability of the magnets was effectively improved with the intergranular addition of Dy80Al20 alloy. Also, the corrosion resistance was found to be improved through small addition of Dy80Al20 powders This was partly due to the stability enhancement of the (Pr, Nd)-rich intergranular phase by Dy80Al20
Coercivity and thermal stability improvement in sintered Nd-Fe-B permanent magnets by intergranular addition of Dy-Mn alloy
No full textTo increase coercivity and thermal stability of sintered Nd-Fe-B magnets for high temperature applications, Dy88Mn12 (wt%) alloy powders were intergranular added into (Pr0.25Nd0.75)(30).6Cu0.15FebalB1 (wt%) starting magnet. The magnetic properties, microstructure and thermal stability of the sintered magnets with different amounts of DyooMn12 were investigated. By adding a small amount of Dy88Mn12, the coercivity was significantly increased from 12.56 kOe to 17.49 kOe. Microstructure analysis showed that a optimized microstructure, i.e. continuous, uniform grain boundary phase was achieved with Dy88Mn12 alloy addition, and Dy was enriched in the outer region of the Nd(2)Fei(4)B matrix grains during the sintering process, which favored to substitute for Nd in matrix grains to form the (Nd,Dy)(2)Fei(4)B core-shell phase. The greatly increased magnetocrystalline anisotropy of the core-shell phase and the improved decoupling by the continuous grain boundary phase accounted for the coercivity enhancement. Furthermore, by adding 0-4 wt% Dy88Mn12, the reversible temperature coefficients of remanence (a) and coercivity (/3) of the magnet were improved from 0.115%/Qc to 0.107%/Qc and 0.744%PC to 0.696%/degrees C in the range of 20-100 degrees C, respectively. In addition, the irreversible flux loss of magnetic flow (h,) decreased sharply as DyooMn12 addition. The temperature-dependent magnetic properties results indicated that with intergranular addition of DyooMn12 alloy, the thermal stability of the magnets was effectively improved.
