Thermal analysis of lubricated three-dimensional contact bodies considering interface roughness

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 2, doi: 10.1007/s11465-022-0672-8

Abstract: Surface roughness and thermal action are of remarkable importance in the lubrication performance of mechanical components, especially in extreme conditions. However, available studies mainly focus on the full-film lubrication conditions without considering temperature rise and real 3D surface roughness due to the complexity of surface topography and temperature characteristics. Moreover, studies on the interfacial thermal behaviors of 3D rough surface lubricated contact in an extended range of working conditions remain limited. In this paper, a deterministic mixed thermal elastohydrodynamic lubrication model considering real 3D surface roughness and thermal effects is proposed. In this model, pressure and temperature are coupled with each other, the computation of elastic deformation is accelerated through the discrete convolution and fast Fourier transform method, the temperature field is calculated with the column sweeping technique, and the semi-system method is introduced to improve convergence and numerical stability under severe conditions. The model is validated by comparing its results with available published numerical and experimental results. The thermal behaviors of the contact interface are studied in a wide range of working conditions. The influences of surface roughness and thermal effect on lubrication performance are revealed. The results show that the proposed model can be used as a powerful analysis tool for lubrication performance and temperature prediction in various heavy-load, high-speed lubricated components over a wide range of lubrication conditions.

Zhaoyun Zhu,Dehuan Fu,Yali Gui,Tao Cui,Jingkun Wang,Ting Wang,Zhizhong Yang,Yanfei Niu,Zhennan She,Li Wang

Frontiers of Medicine 2017, Volume 11, Issue 1,   Pages 32-47 doi: 10.1007/s11684-016-0495-2

Abstract:

One of the primary purposes of the innovative development of ethnomedicines is to use their excellent safety and significant efficacy to serve a broader population. To achieve this purpose, modern scientific and technological means should be referenced, and relevant national laws and regulations as well as technical guides should be strictly followed to develop standards and to perform systemic research in producing ethnomedicines. Finally, ethnomedicines, which are applied to a limited extent in ethnic areas, can be transformed into safe, effective, and quality-controllable medical products to relieve the pain of more patients. The innovative development path of ethnomedicines includes the following three primary stages: resource study, standardized development research, and industrialization of the achievements and efforts for internationalization. The implementation of this path is always guaranteed by the research and development platform and the talent team. This article is based on the accumulation of long-term practice and is combined with the relevant disciplines, laws and regulations, and technical guidance from the research and development of ethnomedicines. The intention is to perform an in-depth analysis and explanation of the major research thinking, methods, contents, and technical paths involved in all stages of the innovative development path of ethnomedicines to provide useful references for the development of proper ethnomedicine use.

A 50-year sedimentary record of heavy metals and their chemical speciations in the Shuangtaizi River

Baolin LIU, Ke HU, Zhenglong JIANG, Fengge QU, Xin SU

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 3,   Pages 435-444 doi: 10.1007/s11783-011-0352-0

Abstract: Two parallel sediment cores collected from tidal flat located in the Shuangtaizi River estuary were analyzed for heavy metal concentrations and chemical speciations. Based on the Cs activity profile, mean sedimentation rate at the sampling site during the past 50 years was estimated to be 1.3 cm·a . Correlation analyses show that almost all the metals are associated with each other, suggesting that these metals might be derived from same sources and/or affected by same geochemical processes. Influence of total organic carbon (TOC) content on the concentrations of Cr, Ni, Cu and Cd is evident. Silt and clay contents, instead of sand content, play an important role in the distribution of these metals. The dominant binding phases for most of the metals (except for Cd) are the residual. The relative decrease of the residual fraction of Cd and Pb in the upper 66 cm of the core is striking. The distribution of chemical fraction confirms that the residual fractions of these metals have a natural origin, while only the non-residual fractions of Cd and Pb increased upward the core due to pollution in the past five decades. Pollution assessment on these heavy metals based on Index of Geoaccumulation ( ) also demonstrates that most of the metals are unpolluted. The weak pollution as observed in the sediments is perhaps related to a local plant, the Kitag, which may have played a significant role in the biodegradation of these metals and the metal distribution in the estuary.

A Dialogue With the Ancient and Reflection on the Interpretation of History of Bian Que and Traditional

Fu Youfeng

Strategic Study of CAE 2005, Volume 7, Issue 12,   Pages 7-16

Abstract:

Based on the description of epidemic diseases in the chapter of “The Story of Bian Que” in Records of Historian, the author has analyzed and explored the truthfulness of its background data and the possibility of the plague spreading at that time from both macro and micro angles. The symptoms of plague including chills and fever, the digestive symptoms and the symptoms in central nerve system made great influence on the formation of some doctrines in traditional Chinese medicine (TCM) such as exopathic heat disease doctrine, internal injury of spleen and stomach doctrine and epidemic febrile disease doctrine. The course of exogenous febrile disease was similar to that of the plague, thus the theory of six meridians was formed. According to above phenomena, the author has explored the effect on the initial medical theory, primitive religion and culture due to the spreading of epidemic diseases from the angles of epidemiology, the theory of images and figures, complicated thought ways depending, as well as archaeological studies. Then the hypothesis of medicine originated from epidemic diseases was proposed. The author also put forward some opinions on the relationship between epidemic diseases spreading and traditional education of TCM, sustained development of TCM education, as well as the integration of TCM and WM.

Avoiding the innovation island in infrastructure mega-project

Hongquan CHEN, Quanke SU, Saixing ZENG, Daxin SUN, Jonathan Jingsheng SHI

Frontiers of Engineering Management 2018, Volume 5, Issue 1,   Pages 109-124 doi: 10.15302/J-FEM-2018073

Abstract: Infrastructure mega-project (IMP) innovation is a complex process characterized by highly diverse innovators, a dynamic life-cycle, and stickiness of innovation knowledge. The IMP’s innovation network can be easily broken due to the fact that the network involves many different innovators across different industries and different projects. Further reasons for the fragility of the IMP’s innovation network are the dynamics of the IMP life-cycle, the diversity of the IMP’s innovative entities, the uniqueness of each IMP, and the temporary nature of each IMP’s organizations. The formed by the breaking of an IMP’s innovation network can stifle and harm innovation performance. Drawing from the knowledge-based view as well as innovation network theory, our research identifies the heterogeneous characte- ristics of IMP innovation. We propose a framework to analyze the formation mechanism of the IMP innovation island from three dimensions—the , the , and the . We look at the Hong Kong-Zhuhai-Macao Bridge project to elaborate the innovation island concept that negatively impacts IMP innovation. We also offer theoretical implications regarding the broader question of how IMPs can manage their innovation in practice.

On the Order Reduction of Dynamics Models of Flexible Spacecrafts

Miao Bingqi,Qu Guangji,Xia Suiqin,Cheng Daosheng

Strategic Study of CAE 2001, Volume 3, Issue 11,   Pages 60-64

Abstract:

The usual mode sets for the dynamics modeling of flexible spacecraft are reviewed. Some mode reduction criterions for the selection of system retained modes are summarized. It is pointed out that the modal cost analysis and the internal balance theory are for the system mode selection and there is the problem how to use these criterions for the component elastic mode or the system elastic deformation mode selection. A tactic for using the order reduction criterions for the dynamics modeling is introduced. An example is given to show the comparison of modeling results with different mode sets and to illustrate how to use the mode reduction criterions for the dynamics modeling of flexible spacecraft.

Liu Xin,Li Chengming and Liu Wenbao

Strategic Study of CAE 2013, Volume 15, Issue 5,   Pages 8-13

Abstract:

To improve the uniqueness location information described by spatial relationship and accuracy of spatial relationship reasoning result,the description model of the integrated topological and directional relations in three-dimensionall(3D) space was developed. The topological directional regions were described by Allen interval pair[(R1,R2,R3)], where R1,R2 and R3 are Allen interval relations between object and reference in X, Y and Z axis projection respectively. According to definition of integrated topological and direction relation, the qualitative reasoning of integrated topological and directional relations were studied. Empirical examples were provided to show the qualitative reasoning process and results of topological direction relationships for some classical cases. Combined tables of the integrated topological and directional relations were obtained when the topological relations were disjoint in 3D space.
