A tuned mass damper (TMD) is a widely used vibration reduction measure in bridge engineering, whose design based on the modal property of structure. As consequence, vibrations certain frequencies are reduced, while some other may be amplified according to methodology TMD. This paper systematically investigates influence these dynamic performance running trains subject earthquake loads. Primarily, bridge-based designed TMD (BBD-TMD) introduced. On this basis, detailed train–track–bridge...
Train‐track interaction (TTI) is a classic research topic in railway engineering, which consists of three main parts, namely, train model, track and wheel‐rail interaction. To improve the computational accuracy broaden application range, an alternative calculation method to investigate TTI based on secondary development technology commercial software ANSYS through APDL language introduced this article. Primarily, train‐track theory briefly presented. On basis, programmed implemented...
Pier settlement is unavoidable in the construction and operation of high‐speed railways. This paper presents a work on influence pier additional structural stress longitudinal connected track (LCT). First all, generation mechanism LCT caused by described detail. On this basis, deformation analytically deduced dynamic model train‐LCT‐bridge coupled system considering established based train‐track‐bridge interaction theory, adopting which stresses are discussed from static perspectives....
Combined double thin‐walled pier is a new kind of adopted in the urban transit system China, whose longitudinal stiffness cannot be determined by adopting traditional methods. Aiming at this practical issue, work proposed an alternative method for determining combined based on train‐track‐bridge interaction. Primarily, relationship between and rail stress underlined, which methodology described detail. Finally, case study conducted to validate effectiveness method. Results show that dynamic...
This paper mainly introduces the communication between computer and S7-200PLC of Siemens, in which host (PC) adopts MSComm control VB6.0, a visual programming language, to implement data console (S7-200 PLC) computer, based on free port protocol. Communication protocol format is user-defined this paper, so huge real time can be implemented conveniently, demand for amount practical system met.
H 2 S adsorption and dissociation on MoP(010) were investigated using density functional theory (DFT) together with periodic slab models. Several different possibilities for S, SH, considered. Our results show that the SH prefer to adsorb at bridge site, while adsorbs preferentially hcp sites. Additionally, optimum co-adsorption configurations SH/H S/H determined. The indicate co-adsorbed species repel each other slightly surface. Finally, potential energy profile of surface was given out....
In China, the rapid development of fast-metro system, along with many dynamic problems in track transition section, threatens safe operation metro system. Aiming at this practical issue, article presents an evaluation on behaviors elastic bars section Primarily, effective global–local method for evaluating performance bar is proposed based vehicle–track-coupled dynamics, which two important models are established, namely, vehicle–track section–coupled model and three-dimensional finite...
