Abstract: Denoising is an essential step in creating perfect point-sampled models, which are widly used in the field of product Design. As the bilateral mesh deoising method by Fleishman has been extended to 3D point-sampled model, which is not efficient enough. For the reason, a method is proposed that using the quasi-Cauchy kernel to replace the Gauss kernel used in the bilateral filtering algorithm, so that the efficiency of the algorithm is improved. Experiments show that the method can eliminate the noise on the surface of the point-sampled model effectively and meanwhile the sharp features of the surface are preserved well．

Abstract: Completed the finite element static analysis on the crossbeam of a certain type of automatic hydraulic tile press and discussed stress and transfiguration of the crossbeam. The result can provide reference for design, and the discussion will be useful for mechanical engineering.

Abstract: This paper presents the use of the Taguchi method, Computational-Fluid-Dynamics and electromagnetic field analysis to optimize the design of a micro wind turbine for a dental fiber handpiece. An orthogonal array, the signal-to-noise ratio and analysis of variance were used to study the multiple-objectives in the micro wind turbine design. The results showed that: (1) the wire slot fill factor and stator angle have a significant influence on the flow rate, whereas wire slot fill factor and inlet dimensions have a significant effect on the pressure drop; (2) the micro wind turbine reduces electricity usage by 25 watts in a day and produces brightness of 20,000-23,000 lux. The proposed design of the micro wind turbine not only saves energy but also reduces the need for replacement halogen lamp.

Abstract: The objective of this work is to determine the strength of the adhesive injected into the gap between the bearing and actuator arm surfaces under changes of nozzle position on the X and Y axis from the reference position using a finite element model. In this study, maximum stress and maximum shearing stress are used to indicate the adhesive strength. The minimum safety factor then is calculated to show the ratio of the yield strength to the maximum strength. The volume fraction is used to estimate the amount of adhesive on both parts of the bearing assembly. The result show, the maximum stress and strain peak for the case (0.25, 0.2) mm, σ_max= 554.4 MPa, τ_max= 319.6 MPa and Sf_min= 0.10. Setting the nozzle position to coordinates (0.2, 0.3) mm gave the lowest stress, σ_max= 69.0 MPa, τ_max= 39.2 MPa and Sf_min= 0.63. The nozzle position significantly affects the adhesive strength. If the nozzle is moved closer to the actuator arm, the stress distribution is better than placing the nozzle near the bearing. Therefore the suitable position for injection is (0.20, 0.30) mm, while the worst poor position is (0.25, 0.2) mm.

Abstract: Based on hydraulic driving technology, this paper designs a novel hydraulic driving drum for belt transfer machine. The hydraulic motor installs inside the drum, which can direct drive the drum and don’t need to decelerate. The hydraulic driving drum has compact structure and a wide speed control range, which is adaptable to drive the belt transfer of the roadheader substituting traditional electric driving drum. It can improve the tunneling efficiency of coalmine and ensure mining balance.

Abstract: Broken silk thread is one of the numerous fancy yarns, and has been used in development of yarn-dyed textiles. However, the processing technology of traditional broken silk thread is very complex, and has restricted its wide application in the development of new textile products. Therefore, the aim of this paper is to develop a novel spinning technology of broken silk fancy yarn. Some examples of broken silk thread, which spun silk or cotton yarn is used as core yarn and binding yarn, polyester filament is as used as effect yarn, are spun on the ring fancy yarn twisting machine, and physical properties of these fancy yarns are tested and analyzed. The better technical program about choice of fiber material on the fancy component yarn and technological processes is put forward, and some tips on the operation are also given.

Abstract: There is representative part among convenience items which increase convenience of driver while part that driver contacts most and recognizes easily sensuously among this convenience function drives into vehicles seat part. On high-reliability, high-tech of vehicles, convenience function in seat part is expanded greatly. Air conditioning ventilation system that can keep temperature comfortable environment on deluxe car among them is raised by important convenience function. This paper deals with a design of the seat cooling fan for vehicle, especially brushless DC (BLDC) motor and blade for cooling fan module. We achieved blade flow analysis about high effectiveness and presented various design data. We have used the 2D Finite Element Method for calculating the characteristics of brushless DC (BLDC) motor, computing fluid mechanics (CFD) as numerical analysis for blade design.

Abstract: At the high altitude, the construction of wind-solar-diesel hybrid power station is a effective measure to solve the problem of power supply in remote areas. Combining with the local natural resources, in order to ensure the reliability of the power supply and heighten the price-performance ratio of the system, designing the wind-solar-diesel hybrid power station in reason is of great significance for increasing the prevalence rate of the wind-solar-diesel hybrid power station.

Abstract: The domestic cast stone industrial production is of high energy consumption and low productivity, so a new cast stone roller kiln is firstly developed. A combustion control approach is advanced to accommodate the new roller kiln architecture and meet the combustion control requirements. Continuous proportion and pulse control methods are adopted to the high-speed isothermal burners with internal dense distribution. Two controllers mutually collaborated in pairs to obtain the internal uniform temperature. The implementation of the combustion control scheme is put forward. The application results demonstrated that the new roller kiln and combustion controller could effectively decrease the furnace temperature difference, increase stability of the combustion atmosphere, improve product quality, reduce energy consumption and NOx emissions.

Abstract: In order to improve the efficiency of solar module, we have designed the Fresnel lens concentrated system and charging system, their schematic diagrams are depicted detailed in this paper. The experimental data show that adding Fresnel lens parts can improve the solar panels' power from 130% to 200% and incident angle can affect solar panels' voltage current characteristic deeply. All of these results can give some support to design the tracking system.
