The optimal placement of sensors and actuators in active vibration control of flexible linkage mechanisms is studied. First, the vibration control model of the flexible mechanism is introduced. Second, based on the concept of the controllability and the observability of the controlled subsystem and the residual subsystem, the optimal model is developed aiming at the maximization of the controllability and the observability of the controlled modes and minimization of those of the residual modes. Finally, a numerical example is presented, which shows that the proposed method is feasible. Simulation analysis shows that to achieve the same control effect, the control system is easier to realize if the sensors and actuators are located in the optimal positions.

Electrospinning technique is currently one of the most important methods for preparing nanofiber. Aiming to the fact that the electric field at the receiver is relatively weak, the electric field’s distribution in the typical electrospinning device was calculated and analyzed by ANSYS. It put forward the method of optimizing electric field’s distribution by using an assistant electric field device. At the same boundary conditions, the electric field’s distribution in the original device and improved binode device are compared. The simulation analysis provides an effective reference for the optimization design of electric field’s distribution in the electro-spinning device. The experimentation results show that the distribution of fiber diameter of polyimide non-woven fabric is equal and has a certain directivity after adding assistant electric field.

In additional to transfer the torque safely, the coupling of the diesel generator set should also has the function of compensating the relative offset distance between the centre line of the diesel crank shaft and the centre line of the generator rotor axis. In this paper, a new type of metallic-disc flexible coupling for diesel generator set of 500kW power was designed. The working principle of the metallic-disc flexible coupling was expounded in detail, and the comprehensive force performances of the metallic-disc were also analyzed. The simulation analysis was carried out to determine the optimal numbers and thickness of the metallic-disc using ANSYS software. So, the needed torque and the coaxiality between the two axes can be guaranteed. The relevant results can provide some guidance for the improvement design of domestic diesel generator set.

With the rapid development of economic society, more and more people are suffering from the huge pressure that comes from all aspects. So many kinds of diseases have higher morbidity than before. Among these diseases gallstone is paid more attention because of its generality. To design a new type instrument that can dissolve cholesterin gallstone directly through peristaltic pumps controlled by industry compute and high speed Analog/Digital (A/D) and Digital/Analog (D/A) card. The instrument can regulate the amount of solvent automatically in order to adapt to the cholecyst according to the treatment parameter given by manipulator and the pressure of patients' cholecyst.
