As the end point of power delivery, a distribution system is directly connected with the consumers. It has complex structures and various operation modes which make the reliability even more important. However, the traditional FMEA cannot be applied to the complex distribution system which contains ring networks. Taking the capacity constraint of distribution system into consideration, this paper...
Addressing problems of larger volume of harmonic gear in the conventional design, in this paper, a mathematical model of optimization with hybrid discrete variables is proposed by taking the modulus of harmonic gear transmission parameters m, the length of flexspline L, wall thickness δ and tooth width of flexspline b as design variables, and the sum of volume of circular spline and flexspline as...
The increased amount of redundant units means improvement of task reliability, however, the additional units and corresponding vote devices request more logistics, which results in decline of basic reliability. In this paper, we design and make analysis and comparison of multiple redundant structures in two ways of task reliability and basic reliability. This paper provides theoretical reference for...
Redundancy technology is widely used as an effective design technique in improving task reliability and safety of system. However, the increasing units result in depression of basic reliability. To keep a balance between these two targets is one of the main aspects in redundancy design. In this paper, we establish game model of FCS reliability using static game theory with incomplete information,...
Based on the understanding of the flight control system of built-in test (BIT) structure, it gets a summary about the cause of the flight control system about generating false alarms, and analyzes the sensing layer during the information processing of the BIT system. Then put forward a method for sensor fault diagnosis which is based on observer in the sensing layer, then isolate the fault timely...
As the end point of the power system, a distribution system directly connects with the consumers. The reliability of power supply is directly related with consumers. However, uncertainty of the original parameters of components may be caused by lacking of statistical information and the statistic error. It will inevitably produce large errors if we directly use these parameters for evaluation. The...
Interval analysis and probabilistic method are investigated in this paper for compressive bar's stable responses with uncertain parameters. According to the set relationships and probability statistics theory, the relationship between above two methods can be analyzed by introducing Chebyshew inequality. Took compressive bar in certain equipment for example, analyzed it with interval analysis and...
