The application of ergonomics in the tractor modeling has experinced three phases. They are design phases of mechanical center, “man-machine” system and “man-machine-environment” system. In the design phases of mechanical center, only considered mechanical design in terms of mechanics; In the design...

Increasingly, heat flux density on one chip reached to 1KW/cm2 with the development of integration technology. However, it is hardly to meet the demand of 417K for conventional cooling way. Chip cooling become the bottleneck of integration further. This paper put forward that integrated micro channel...

The structure characteristic of the main reducer of one rear drive automobile was introduced in this paper, and also the bearing preloads effect on the supporting stiffness of main reducer was discussed. Analyzed the calculation of bearing preload theoretically, and compared it with the simulation through...

Combined with artificial neural network of good features, using the orthogonal experiment data obtained as the training sample of neural network we established a neural network model of the input for the process parameters, output for the springback amount, and the accuracy of the ANN model was verified...

To enhance 5-axis CNC machining precision of complex surfaces with a ball-end cutter, the generation method of cutter contacting (CC) paths is presented in this paper. By means of curvature circle, the feeding length was calculated within allowable error. The step-over in the perpendicular direction...

Fused Deposition Modeling (FDM) is one of the most widely used additive manufacturing processes for fabricating prototypes and functional parts in common engineering plastics. From the view of the control structure, 3D printer based on the FDM technology is divided into two layers: the host computer...

Fire resistance for steel framed buildings is very important not only to guard lives that live and visit but to sustain the structural stability to prevent falling down. To evaluate and compare the fire resistance of long span beams built with ordinary structural steels, fire engineering method using...

This study investigated the use of nanoscale bilayers assembly for superhydrophilic and superhydrophobic surface modification on stainless steel plate. This study performed nanoscale bilayers assembly method ,as well as chemical vapor deposition (CVD) to perform fluorosilan treatment on the modification...

This study introduces the principles and application procedures of the stiffness multiplier method used to correct the statistical energy analysis (SEA) subsystem attributes. Using the cockpit floor of a certain type of fighter aircraft as an example, this study combines the finite element method and...

The percussion instrument usually involves some kind of striking. There are so many Thai percussion instrument such as the Ranat, the Cymbal ect. The aim of this analysis to study transverse modes and find out the important parameter to get proper sound frequency which are excited in bars that are struck...

Taking lining structure crack diseases on one line of Beijing subway as the research object, using indoor model test method to studying lining structure damage rule and crack maintenance effect. Through experiment, it was concluded the main conclusions as follows: Through the contrast test could be obtained...

Computer vision imitates human vision ability to perceive real world. Computer vision has proven its part from autonomous navigation on martin surface to histopathology images recognition. In practice, histopathologists examine microscopic imagery of diseased tissue and diagnose on the bases of malignancy,...

To resolve the extra workload of spindles’ preparation, image measurement method was applied in various part measurement of geared ring radial runout without spindles. An experiment was made to explore the errors and uncertainty of gear measurement through image measurement .By analysis of data, the...

In order to analyze the error sources of circular gratings angle-measuring system, a series of coordinate systems were established on the gratings angle-measuring system through taking many mechanical errors into account, such as rotary errors of the axis system, installing eccentricity and tilt of circular...

This paper investigates the effect of using unleaded gasoline with di ethyl ether blends on spark ignition engine (SI engine) performance, exhaust and combustion analysis. A four stroke, single cylinder SI engine was used for conducting this study. Exhaust emissions were analysed for carbon monoxide...

The aim of this paper is to discuss success criteria of oil, gas and petrochemical projects and developing a pattern for evaluation of these projects. It is conducted following a case study approach in which the projects of Arya Petro Gas Co. are examined. The methodological framework of this research...

This research is based on Taiwan’s first zero-carbon green building-Magic School of Green Technology in National Cheng Kung University. Actual energy consumption will be measured to explore benefits of energy-saving. The design origin for this building encompasses 13 green energy-saving techniques. United...

Environment problems have drawing more and more attention in recent years,the ecologic restoration engineering of slope have progressively increased too.As a result, the engineering is needed to be assessed. Now,a lot of methods which macroscopicallyassesse that in all respects are used, but this paper...
