A novel model of high-loading complex structure FGB sensor are presented, through the analysis of the structure design principle of the cantilever beam optical fiber grating weighed sensor, using the ANSYS to simulate and calculate the structure of the sensor's elastomer. Under the constant-load, comparing and analysing the different changes of the stress state and the radial displacement, caused by different thickness of elastomer and diameter of hard center, finds that, when the elastic thickness is 10 mm and the hard center diameter is 75 mm, the designed elastomer meets the application of weighed sensor for large crane, the experimental results of loading/unloading experiment verificates the conclusion of ANSYS. This sensor has been used in the 2600 t large marine floating crane for the dynamic measurement of high-loading almost a year, this shows the effectiveness and practicality of this research. Source

The bending behavior of laminated glass was analyzed using negative uniform pressure test. The laminated glass consists of two monolithic 5 mm float glass and joints with 0.38 mm PVB interlayer. The dimension of laminated glass is 1000 mm × 1000 mm. It indicated that the center deflection of the laminated glass increased from 4.15 mm to 5.16 mm and the center maximum stress increased from 8.94 MPa to 10.50 MPa with the environmental temperature raised form 18°C to 35°C. The fit curves of the center deflection and maximum principal stress of laminated glass with temperature was given. Source

The AZO thin film with different Al-doped deposited at 400°C on the glass slide by ultrasonic spray pyrolysis. The optics and electricity character of the film were studied. It was shown that the doping of Al effect the optics and electricity character of AZO film. The AZO film has few surface defects, transparent of coated glass achieved 84% and sheet resistance is 60 Ω/□ when Al doping is 4at%. Source

This project aims to study the optimal control model of the ice-storage system which is theoretically close to the optimal control and also applicable to actual engineering. Using Energy Plus, the energy consumption simulation software, and the simple solution method of optimal control, researchers can analyze and compare the annual operation costs of the ice-storage air-conditioning system of a project in Beijing under different control strategies. Researchers obtained the power rates of the air-conditioning system in the office building under the conditions of chiller-priority and optimal contro1 throughout the cooling season. Through analysis and comparison, they find that after the implementation of optimal control, the annually saved power bills mainly result from non-design conditions, especially in the transitional seasons. © (2013) Trans Tech Publications, Switzerland.

The crystallization process and kinetics of ultralow-expansion lithium aluminosilcate glass ceramics were investigated using differential scanning calorimetric (DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM) and other measuring technologies, and the effects of phosphate on the crystallization mechanism and structure of glass ceramics were analyzed. The results show that the introduction of phosphorous can influence the glass phase separation and phase transition process. On the one hand, phosphorus pentoxide can be as effective nucleation induction agent to result in phase separate, which is beneficial to the nucleation and crystal growth; on the other hand, it can increase the crystallization active energy (E), make glass network structure rearrange difficultly, and restrain the grain growth.
