Strategic Study of CAE 2010, Volume 12, Issue 3,   Pages 15-21

Abstract:

High-speed railway represents the developing direction of railways in the world. Systematically researching the basic theories, engineering construction and operation practice of high-speed railways in China has great significance to speed up the construction of world-classhigh-speed railway sandrealize the strategic target of“going-out” for China' s railway technology.Based on alarge quantity of the oretical and testing researches and construction practices, this paper systematically researched the main design standards of high-speed railways in China,
and the comprehensive testing results of Beijing-Tianjininter-city railway and Wuhan-Guangzhouhigh-speed railways how the main technology standards can satisfy the safety and stability requirements of 350 km/h railways and the quality of lines reaches world advanced level.

Research on the ecological compensation standard of the basin pollution control project based on evolutionary

Dongbin HU, Huiwu LIU, Xiaohong CHEN, Yang CHEN

Frontiers of Engineering Management 2019, Volume 6, Issue 4,   Pages 575-583 doi: 10.1007/s42524-019-0044-1

Abstract: Ecological compensation is a new resource and environment management model. As one of the main areas for implementing ecological compensation policies, basin ecological compensation has become an important measure for encouraging basin pollution control projects and improving the quality of regional economic development. By applying the basic game analysis of evolutionary game theory and building an evolutionary game model with a “reward–punishment” mechanism, this paper compares the interest-related decision-making behaviors of the upstream and downstream stakeholders of basin ecological compensation. By using data on the water quality of Xiangjiang River Basin, this paper calculates the rewards and penalties in different intervals by building a parametric regression mathematical model and employing the local linear regression method. Results show that a decline in water quality should be fined RMB 925500 yuan, an improvement in water quality should be awarded RMB 1227800 yuan, and a deteriorating water quality should be severely fined RMB 5087600 yuan.

A Further Discussion on Trends in the Development of Advanced Manufacturing Technology

YANG Shu-zi, WU Bo, LI Bin

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 1,   Pages 1-5 doi: 10.1007/s11465-005-0002-y

Abstract:

This paper is a supplement to Trends in the Development of Advanced Manufacturing Technology (Yang and Wu in Chin. J. Mech. Eng., 39: 73, 2003) but delves deeper into it. It first points out the strategic status of manufacturing industry in state development. Then, a detailed analysis is given on the features and trends in the development of advanced manufacturing technology in a total of 12 points from three aspects: precision, extreme, and culture from the aspect of the product itself; green, rapidness, saving, and efficiency during the manufacturing process; and digit, auto, integration, networking, and intelligence in view of the manufacturing method. In addition, it emphasizes that all the above aspects should be based on two base points: manufacture and machinery. Finally, it puts forth the guiding ideologies for the development of advanced manufacturing technology and the aspects China should give priority to in development, while stressing on the principles of independence, innovation and human orientation.

A preliminary analysis and discussion of the condominium building collapse in surfside, Florida, US,

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5,   Pages 1097-1110 doi: 10.1007/s11709-021-0766-0

Abstract: On June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered a sudden partial collapse. This study analyzed the overall performance and key components of the collapsed building based on the building design codes (ACI-318 and GB 50010). Punching shear and post-punching performances of typical slab-column joints are also studied through the refined finite element analysis. The collapse process was simulated and visualized using a physics engine. By way of these analyses, weak design points of the collapsed building are highlighted. The differences between the reinforcement detailing of the collapsed building and the requirements of the current Chinese code are discussed, together with a comparison of the punching shear and post-punching performances. The simulated collapse procedure and debris distribution are compared with the actual collapse scenes.

Frontiers in Energy 2019, Volume 13, Issue 3,   Pages 579-589 doi: 10.1007/s11708-018-0557-z

Abstract: This paper establishes an irreversible Dual-Miller cycle (DMC) model with the heat transfer (HT) loss, friction loss (FL) and other internal irreversible losses. To analyze the effects of the cut-off ratio ( ) and Miller cycle ratio ( ) on the power output ( ), thermal efficiency ( ) and ecological function ( ), obtain the optimal and optimal , and compare the performance characteristics of DMC with its simplified cycles and with different optimization objective functions, the , and of irreversible DMC are analyzed and optimized by applying the finite time thermodynamic (FTT) theory. Expressions of , and are derived. The relationships among , , and compression ratio ( ) are obtained by numerical examples. The effects of and on , , , maximum power output ( ), maximum efficiency ( ) and maximum ecological function ( ) are analyzed. Performance differences among the DMC, the Otto cycle (OC), the Dual cycle (DDC), and the Otto-Miller cycle (OMC) are compared for fixed design parameters. Performance characteristics of irreversible DMC with the choice of , and as optimization objective functions are analyzed and compared. The results show that the irreversible DMC engine can reach a twice-maximum power, a twice-maximum efficiency, and a twice-maximum ecological function, respectively. Moreover, when choosing as the optimization objective, there is a 5.2% of improvement in while there is a drop of only 2.7% in compared to choosing as the optimization objective. However, there is a 5.6% of improvement in while there is a drop of only 1.3% in compared to choosing as the optimization objective.
