This paper investigates the production tolerances and variations of the lamination and permanent magnet on the cogging torque of the surface permanent magnet (SPM) machine with mass production. The finite element analysis (FEA) and experiment contrasted analysis method is adopted to deal with the additional component cogging torque, of the 12 slots 10 poles combination SPM machine, caused by production variation of the magnet, stator and rotor lamination. Its reveal that the eccentricity has small effect on the cogging torque, however, the manufacturing tolerances of lamination and inconsistency of permanent magnet have more significant influence on the cogging torque. This paper also propose the method by successively rotating each lamination of stator and rotor to suppress the additional components of the cogging torque.

Considering the problem that the original chicken swarm optimization algorithm is easy to fall into local optimum because of premature convergence for high-dimensional complex problems, an improved chicken swarm optimization was proposed. In this algorithm, the part of chicks learning from the rooster in their subgroup is added to chick's position update equation, and the inertia weight and learning factor are also introduced. Then eight benchmark functions are used to test the proposed algorithm and the comparison with particle swarm optimization, bat algorithm, and original chicken swarm optimization are also performed. The simulated experimental results showed that the proposed algorithm is able to avoid premature convergence and therefore can escape from local optimum. Especially, the proposed method outperforms other evolutionary algorithms in finding the global optimum for high-dimensional problems.

Considering the pitch sensor fault of pitch systems in wind turbines, a multi-innovation observer based fault detection method is proposed. The pitch system can be modeled as a second order differential equation. And then the equation is transformed into a state space model. According to the state space model, a multi-innovation observer is designed to estimate the system state. The pitch sensor fault can be detected through the residual which is generated by comparing the state estimation with the output of an actual system. The simulation results show that the proposed approach is able to detect the pitch sensor fault effectively.

The aim of this paper is to investigate the time dependence distribution of workpiece cutting temperature in milling process. An experimental system used to achieve a measurement of cutting temperature in high speed milling is designed by use of the thermocouple and infrared thermal imager. The general regularity of temperature distribution is concluded, and the influence of the process variables such as cutting speed, cutting depth, etc. on the temperature distribution was investigated in detail. All the experiment results can be effective used to develop a new non-contact soft-sensing method for high speed cutting temperature prediction. © (2014) Trans Tech Publications, Switzerland.

The ability of acquiring and processing information in manufacturing influences agile of manufacturing system. According to the idea that networked field information processing is realized based on intelligent nodes of field-bus technology, distributed intelligent field information processing flow is researched to synthesize multiple functions such as information gathering, information processing, warning system and field control. The method of information represented and collected was put forward. The multilayer data fusion model of distributed intelligent field information processing is built. Then the distributed LonWorks fieldbus monitoring model (DLFMM) based on LonWorks fieldbus technology is established. A monitoring system of a rail vehicle automatic door factory is shown as an example to illustrate design strategy of monitoring system based on DLFMM. This monitoring system shows that the model of distributed intelligent field information processing, DLFMM and the extraction and representation of information flow discussed in this paper are reasonable and applicable. © (2014) Trans Tech Publications, Switzerland.

This paper attempts to use a simple and practical method based on the finite element theory for the optimal structural design of machine tool bed. The higher is the natural frequency of structure, the better are static and dynamic structural stiffness. Dynamics finite element model of CA6136 machine tool bed has been established with the finite element analytic technique in order to improve the dynamic characteristics. Then, two improved bed design schemes based on unit structure (US) are presented and analyzed by comparison using natural frequency and the total mass of structure as target. The simulation results indicate that the method is simple, effective and feasible. The method also can be applied to other dynamic structural design. © (2014) Trans Tech Publications, Switzerland.
