Abstract:Reference efficiency of a pair of gear drive without planetary motion is the base to calculate efficiency of the whole planetary gear train. The authors find reference efficiency for speed increase is higher than that of the same drive used for speed reduction. This is different from the earlier viewpoint. New equations are derived for correctly calculating the reference efficiency of spur gear and helical gear with internal conjugate and external conjugate either in the state of speed increase or speed reduction respectively. The equations are also used to calculate efficiency of 2K-H planetary gear train.

Abstract:In order to optimize disassembly sequence about wornout or malfunctioning products,firstly,it is proposed to build Interference-Freeness Matrix for describing the structure of assembly.Secondly,computing model of automatic generating and optimizing disassembly sequence of assembly is proposed based on Genetic Algorithms.Then,after inputing some disassembly sequences and other controlling parameters,the program can search optimizing disassembly(sequences) valid in geometry.Minimal reorientation number of times during disassembling assembly is assigned as optimizing objective.At last,because the neighborhood may converge too fast and limit the search to a local optimum prematurely during the process of Genetic Algorithms(GAs),the authors combine the strengths of GAs and Tabu search and presented the detailed flow chart of the hybrid approach.More robust search behavior can possibly be obtained by incorporating the(Tabu's) intensification and diversification strategies into GAs.The details of the hybrid approach and a case study are presented here.Much engineering examples is tested to demonstrate the approach.The results given show that the valid disassembly sequences obtained are superior to those derived from GAs alone in fitness value,number and distribution.

Abstract:The accuracy of transformer substation state estimation is widely low,and one reason of that is inaccurate(parameter) of model.Recently,most of papers about state estimation(SE) focus on improving algorithm.Based on classic SE and parameter estimation(PE),this paper takes advantage of the methods that putting parameters into state vector and putting parameters both into state vector and measurement vector in discussing the influence of parameter on transformer substation SE via simulation.The result of simulation shows: First,the error of parameters will be too high if only putting them into state vector,although the result of SE will be much better.Second,putting parameters both into state vector and measurement vector and giving them appropriate coefficient will lead a better result that can be used by engineering.

Abstract:The authors analyze the influence in vector controlled induction machine caused by parameter variation and main flux saturation affects speed estimation of adaptive state observer. According to simulation of the modified scheme with saturated induction motor model, it is proved that when the vector control scheme operates in field weakening region, the main flux saturation will obviously influence precision of speed observer and bring great error of speed estimation. Thereby, the main flux saturation should be compensated to improve performance of the vector control system.

Through analysing the period of toms automorphisms which is a prototype of chaotic map, and making use of the framework of the traditional public-key algorithm RSA, the authors propose a chaotic public-key encryption algorithm based on toms automorphisms. Its security is based on the intractability of the integer factorization problem as RSA, and it is able to resist the chosen-ciphertext attack against RSA and easy to be implemented.

Abstract:The locally twisted cube is a newly topological structure of network. The authors we design a unicast fault-tolerant routing algorithm on the locally twisted cube by utilizing safety levels and the feature of the network. The performance of the proposed algorithm is evaluated through simulation experiments. When the number of faulty nodes reaches or exceeds half of the total, it can still achieve a quite high percentage of successful routing. An additional advantage of the routing algorithm is that it is highly probable that the selected route be a shortest route between the associated nodes.
