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.

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.

Description and reasoning of integrated topological and directional relation of bodies in 3D space

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.
