Starting with the domain walls changing of magnetization process for the cable tension sensor, the influence mechanism is studied between temperature and magnetization. In this paper, making Jiles-Atherton (JA) model as the theoretical basis and introducing the Curie temperature as additional parameter, a magnetic-thermo coupling model for the magnet elastic cable tension sensor is constructed by analyzing the temperature and the physical parameters of the model, followed that, a mathematical analysis is used for the model as the stress or temperature is changing. Compared the analytical results, the effects of the temperature to magnetization is obvious when the sensors is in magnetization rising or decline stage, and a reasonable magnetization working point not only can reduce the interference but insure the sensitivity to stress changing of the sensor.

In order to improve the cleaning efficiency of curtain wall, a pneumatic robot is designed. The robot is consists of mobile system, adsorption system and cleaning system. The mobile system is a cross-shaped framework that is driven by the pneumatic system and moves mutually. Vacuum sucker scheme is adopted in the adsorption system. Cleaning brush is driven directly backward and forward by the cylinder. The adsorption and detachment of robot feet sucker, body movement and sequence control of the robot cleaning task are controlled by the PLC. The function that robot can clean glass curtain wall efficiently by the harmony operation is achieved.

Magneto-elastic cable tension sensor have a number of advantages, it will be ideal method to measure cable tension in large span cable-bridge, but the sensor is sensitive to temperature, so the temperature influence is not negligible to sensor. In this paper, the principle of cable tension sensor based on magnetic-elastic effect is introduced, the common temperature compensation technique are detail analyzed. A novel method of temperature compensation by adjusting the bias magnetic field is put forward, by theoretical analysis and experiment, indicated that it is feasible to compensated the temperature influence.

In order to meet the demand of hydraulic experiment teaching in universities, base on the analysis of the function of virtual hydraulic experimental system, the main research contents、 system scheme and key technology are determined. Three-dimensional model of the hydraulic components are established. Working principle of hydraulic component is displayed. The action process and the performance of the hydraulic circuit are simulated. A virtual hydraulic experimental system with its own characteristics is built. The virtual experiment system is not only suitable for classroom teaching but also suitable for the experimental teaching and learning activeness of students is enhanced by using the system.

In order to solve the deficiency of existing rehabilitation robot a novel upper limb rehabilitation robot structure is designed. Kinematics model is established by the method of Denavit-Hartenberg. The robot is driven by pneumatic muscle. Simulation on the robot movement is carried out by the simmechanics of matlab. When the joint is driven, the angle、angular velocity and working space of robot are all obtained. Feasibility of the robot design is confirmed by the simulation results.
