The aim of the present study is to clarify the thermal performance of the radiant cooling system with Water Flow on Roof, which employs the evaporative cooling effect on the roof surface. In this paper, the thermal performance of this system is discussed from a point of view of the coefficient of performance, using a test house. Measurement results reveal that the indoor globe temperature of the test room is kept below 28 °C on summer days when the maximum outside temperature exceeds 30 °C. The COP varied from 0.9 to 5, in the experiment periods.

In experimental research, we first measure the exact thickness of the solidified carbon fiber-reinforced plastic (CFRP) with the three-coordinate measuring machine, then use Shimadzu testing machine to measure elastic modulus and shear modulus of the adhesive; We do static test on H-shaped steel girder reinforced by CFRP which has different thickness, and paste strain foil on the surface of CFRP to record the change of strain and place the displacement meter in the middle of the span to observe the deformation. Making use of the performance parameters of composite materials, we use finite element method for H-shaped steel girder reinforced by CFRP to make simulation analysis, put forward truss element simulation of bonding layer, “Shell element-Truss-Entity”of CFRP reinforced H-shaped steel girder simulation of composite component model to simulate experiments, and obtain load-deflection curve, ultimate strength and deformation of reinforced composite component. The test results agree well with numerical simulation results and the comparison of the results shows that the proposed modeling approach and the experimental program is feasible, so they will provide reference for CFRP reinforcement in steel structure in the future.

The article briefly analyzes the vibration mechanism of the gear fault and kinds of typical signal characteristics of the gears, and introduces successive fuzzy reasoning into the fault diagnosis of the gears. For the selection of characteristic parameters, we used the discrimination index DI to evaluate the identification ability of the characteristic parameters, and select the characteristic parameters of the largest value of DI. According to possibility theory and statistics and probability theory, we replace the original feature parameters into feature parameters of known distributional, and then equate the membership function used in fuzzy reasoning. Finally, the given diagnosis instance indicates that it is effective and feasible to use the method of successive fuzzy reasoning in the fault diagnosis of gears.

A family of spherical parallel mechanisms which have fully decoupled motions is presented in this paper. The condition required for synthesizing the fully decoupled parallel mechanism is derived from the screw formulation of Jacobian matrix. According to this condition, several novel decoupled spherical parallel mechanisms are obtained. The decoupled motions are validated by the simulation of the prototype of spherical parallel mechanism.

The paper presents a relative novel time-frequency analysis method which applies in the vibration Fault analysis of rotor systems through Hilbert spectral analysis (HSA), the part of the Hilbert-Huang transform. Using this method we analyze the vibration fault characteristics of the rotor system with rub-impact by compared with non-rubbing rotor system both in experiment and simulation. Firstly, a single-span-two-disc test rig of rotor system with rub-impact at fixed limiter is established, and corresponding simulation model is built by finite element method (FEM). Then, system experimental and simulation signals at non-rubbing and rubbing condition are obtained based on the experiment and the FE model simulation, moreover which are analyzed by using HSA along with shaft center orbit method. The results show that the proposed method is effective in the vibration Fault analysis of rotor systems. Some conclusions are achieved which will be useful in the detection of rub-impact fault of rotor systems.
