Zhao, X. (author), Huang, Shuangchao (author), Yin, Shan (author), Yang, Jizhong (author), Yang, Z. (author), Tao, Gongquan (author), Wen, Zefeng (author)A time-domain finite element model is developed to study the transient rolling contact of a driving wheelset over a curved track with Low Adhesion Zones (LAZs) shorter than 1.0 m. LAZs on one rail, i.e., unilateral LAZs occurring more likely, is treated for a speed up to 500 km/h. Structural vibrations of wheelset are analyzed to explain the...journal article 2023

Zhao, X. (author), Bai, Shunwen (author), Tu, Yinan (author), Zhang, X. (author), Spanjers, H. (author)Life cycle assessment (LCA) has proven to be a useful tool in assessing environmental technologies in a retrospective manner. To fully uncover the environmental improvement potential while advancing technologies under technical and environmental constraints, this study recommended approaching the LCA proactively to assess the progress of...journal article 2020

Zhao, X. (author), Verhagen, W.J.C. (author), Curran, R. (author)The present study proposes an economic indicator to support the evaluation of aircraft End of Life (EoL) strategies in view of the increasing demand with regards to aircraft decommissioning. This indicator can be used to evaluate the economic performance and to facilitate the trade-off studies among different strategies. First, Disposal and...journal article 2020

Zhao, X. (author), Yang, Jixian (author), Ma, Fang (author)For wastewater-related issues (WRI), life cycle assessment (LCA) is often used to evaluate environmental impacts and derive optimization strategies. To promote the application of LCA for WRI, it is critical to incorporate local impact of water pollutants. Organic pollution, a main type of water pollution, has not been given much consideration...journal article 2018

Zhao, X. (author), Wang, Li (author), Du, Linna (author), Yang, Jixian (author), Dong, Jing (author), Ma, Fang (author)The increasing salinity in aquatic environments has had a negative impact on the biodegradation of atrazine, an extensively used herbicide which has been proven to pollute soil and water ecosystems. In the present study, a novel atrazine-degrading strain (ZXY-2) was isolated from industrial wastewater and identified as the Arthrobacter genus...journal article 2017

Li, Z. (author), Zhao, X. (author), Dollevoet, R.P.B.J. (author)A methodology for the determination of a critical size of surface defects, above which RCF can initiate, has been developed and demonstrated with its application to the passive type of squats under typical Dutch railway loading conditions. Such a methodology is based on stress evaluation of transient rolling contact at the defects, for which...journal article 2016

Zhao, X. (author), Verhagen, W.J.C. (author), Curran, R. (author)The present study develops a method for the sake of evaluating Disposal and Recycle (D&R) cost in view of the increasing demand in aircraft retirement. Firstly, a process model is extracted. The subordinated cost elements are also identified. Next, the cost aggregations based on the D&R process steps are discussed. Moreover, it proposes...book chapter 2016

Zhao, X. (author), Verhagen, W.J.C. (author), Curan, R. (author)n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...book chapter 2015

Zhao, X. (author)Consequence of disturbance due to fault of earthing of on-board systems are not always clear. Second, the military EMC standards are outdated and the rationale behind these standards lacks. Therefore, research into rationale of standards and directives related to system earthing on board is necessary; in addition, develop appropriate on-board...master thesis 2014

Van Dijk, R.E.C. (author), Zhao, X. (author), Wang, H. (author), Van Dalen, F. (author)Competitive aircraft box structures are a perfect compromise between weight and price. The conceptual design process of these structures is a typical Multidisciplinary Design and Optimization effort, normally conducted by human engineers. The iterative nature of MDO turns development into a long and costly process. Knowledge-Based Engineering...conference paper 2012

(author)Matching of building polygons with different levels of detail is crucial in the maintenance and quality assessment of multi-representation databases. Two general problems need to be addressed in the matching process: (1) Which criteria are suitable? (2) How to effectively combine different criteria to make decisions? This paper mainly focuses on...conference paper 2012

Zhao, X. (author)Squats, as a kind of short wavelength rail surface defects, have become one of the main rolling contact fatigue problems in railways worldwide. The purpose of this work is to better understand the squatting phenomenon, contribute to reduction and even prevention of squat occurrence, and thereby reduce the related costs. To such an end, a new...doctoral thesis 2012
