As a kind of soft actuation materials, Ionic polymer-metal composites (IPMCs), displaying an excellent capability of converting electrical energy to mechanical energy, are promising applications in robotics and medical devices. In this paper, we introduce a millimeter thickness IPMC actuator with a new patterned configuration. Firstly, a perfluorinated ion exchange membrane with millimeter thickness is fabricated by solution casting process. And then, in order to achieve complex deformation of IPMC actuator, a novel method that rapidly patterns the multiple electrodes and minimizes the damage of the membrane is developed. Finally, initial performances of thick patterned IPMC are measured and characterized by a visual system. The study reveals that multi degree of freedom (MDOF) deformation is implemented successfully by the IPMC with patterned configuration.

Swing characteristic of pads in four-pad tilting pad bearing has been studied systematically with the guide bearing for canned pump motor in fourth generation nuclear power units as object. Theoretical derivation reveals that dimensionless pad pendulum angle depends on structural parameters, preload ratio and eccentricity ratio of the bearing, but is unrelated to viscosity of lubrication oil, shaft rotating speed and clearance. Numerical analysis shows that pad pendulum angle is determined by pad circumferential position, preload ratio and eccentricity ratio. Pad pendulum angle has significant influence on minimum oil film thickness. Pad pendulum angle maybe negative and leads to minimum oil film thickness greater than that of fixed pad. Results of this paper provide basic analysis for safety operation of the canned pump motor in fourth generation nuclear power units.

A MEMS (Micro-electro-mechanical systems) fluid viscosity sensor with resonant trapezoidal micro cantilever is introduced in this paper. The fluid viscosity can be measured through the relationship between the fluid viscosity and the quality factor, the resonant frequency of the micro cantilever immersed in the fluid. In order to improve the sensitivity of the viscosity sensor, the geometry of the sensor chip should be carefully designed. Rectangle and trapezoidal micro cantilever chip with different lengths are proposed. The first resonant frequencies and harmonic response analyses of two sensor chips are carried out with ANSYS software. And the quality factors of the sensor chips are calculated through Matlab software. The simulation results show that the resonant frequency and quality factor of trapezoidal cantilever are higher than that of rectangular cantilever with the same length. Therefore, the viscosity sensor with trapezoidal micro cantilever has a better performance. The experimental results show that the viscosity sensor with trapezoidal micro cantilever has a fine accuracy to measure the viscosity of toluene.

High accuracy of machine tool is the assurance of top-quality products in machining processes. Among the various errors related to machine tools, thermal errors have a significant effect on machining accuracy and directly determine the machined quality of the finished part with both the surface finish and the geometric shape. So, if we establish thermal error model accurately, the affection of thermal error would be eliminated through compensation. How to get the key temperature measuring points and robustness of the model is the main problem of thermal error modelling using traditional methods. Accordingly, the paper presents a novel method for searching key thermal point by means of infrared imaging system and modelling by system identification based on least square principle. The experiments of thermal error compensation have been conducted on a rotary table of five-axis Milling Center. The results show that the key points are selected simply and effectively and the compensation model has good adaptability, thus its prediction is accurate.

In this study, the stability analysis is carried out on a water-lubricated hybrid bearings used as the support of a high-speed motorized spindle. A two-dimension finite element method considering turbulence effect has been developed to solve the nonlinear oil film force. This paper mainly studies the influence of the water supply pressure, rotating speed, and unbalance mass on the axis orbit of the rotor-bearing system. The results of the axis orbit indicate that the effect of nonlinear for the hybrid bearing studied in this paper is not obvious, and the bearing-rotor system can run safely and stably at the rotating speed not more than 30000 rpm.

This paper focuses on the development of an electric spindle integrated with an electromagnetic ring balancer. Firstly the electromagnetic ring balancer is designed and then 3D model of self-balancing spindle integrated with this balance er is created. Based on the design, an on-line balancing principle of self-balancing spindle is proposed. The prototype machine fabrication process of the balancer's key parts including coil, counterweight disc and toothed disc are discussed. For an actual spindle, the detailed design and development of this balancer are done, particularly the balancing craft of the combined rotor is done on a balance machine before delivery. By installing the balancer on the front end of spindle using flange, a self-balancing spindle prototype is obtained. In workshop, the vibration test of the developed self-balancing spindle is carried out in the range of 3000r/min to 9000r/min. The result shows the developed self-balancing spindle has a vibration velocity below 0.5mm/s. Finally the two eddy current sensors are applied to evaluate the vibration suppression capability of balancer, the experimental result is that about 15um peak-peak value can be eliminated when the correction value of balancer changes from 0 to 38.55g.cm in 3000r/min.

The androgynous peripheral driving mechanism is a flexible series multi-body system, of which assembly precision is primarily dependent on worker's experience. In order to improve the assembly efficiency and reduce the assembly cost, a system used to predict the synchronous accuracy for guide assembly is developed based on Matlab-GUI. This system consists of three modules, i.e., data management module, accuracy prediction module and animated simulation module. Each module is briefly investigated in this paper. By predicting the driving mechanism, the theoretical data have been compared with the experimental data. And the synchronous errors of the simulation and animation are also shown on the interface. The results indicate that the predicted values are within the permitted deviation range and agree well with changes of the synchronous errors. Moreover, the prediction system is also of good reliability and stability which can be used to guide the workers for assembly.
