Meshing force of misaligned spline coupling is derived, dynamic equation rotor‐spline system established based on finite element analysis, the influence meshing simulated by numerical integral method. According to theoretical related parameters, misalignment, transmitting torque, static vibration displacement, and so on. The increases nonlinearly with increasing thickness misalignment or decreasing alignment distance (AMD). Stiffness relates not a constant. Dynamic behaviors reveal...
The pipe curtain structure method (PSM) is a novel construction to control ground deformation strictly. Compared with the traditional pipe-roofing and jacking method, connection between pipes in large spacings using PSM widely acknowledged as unique procedure. Further study on this procedure needed resolve similar cases that are inevitably constructed both sides of existing piles. Cutting steel plate during first step, which crucial safety stability surrounding environment structures....
In a mechanical interface, the contact surface topography has an important influence on stiffness. processes of asperities, elastic-plastic change can lead to discontinuity and lack smoothness at critical point. The result is large difference between deformation actual asperity deformation. Based Hertz theory, heights asperities rough obey Gaussian distribution. To take into consideration continuity deformation, we divide three stages: pre-elastic-plastic, mid-elastic-plastic,...
Tidal current turbine is the core equipment to convert tidal energy. In this paper, performance of designed tested in laboratory, then impeller used conduct an experiment on desalination sea water. The test novel has been done BoHai Sea. experimental results indicate that efficiency newly developed could reach up 47.6%; corresponding tip speed ratio from 3.5 6. Under condition big yaw angle, still remain high working efficiency. When velocity exceeds 1.0 m/s, pressure may increase Mpa, and...
A tenon connection structure is widely used for the blade-disk in turbomachinery, and its ability to resist wear influences operation life. The finite element method (FEM) has been extensively applied predicting fretting due advantage solving problems like non-linearity of boundary conditions. This work proposes a model that combines modified Archard with FEM simulate multiple pairs contact curved surfaces structure. considers various factors, including direction fretting, time, load...
This paper presents a theoretical analysis on parallel feed LT-MED desalination system with thermal vapor compressor which is helpful to the design and operation of such kind seawater plant. The mathematical model (TVC) developed basis mass energy conservation equations. In model, temperature loss considered caused by boiling point elevation (BPE) steam flow resistance also included flowing through tube bundle demisters pipelines between adjacent evaporators. property parameters are taken as...

Nonlinear dynamic model of gear coupling is derived, equations rotor-bearing systems connected by rigid coupling, and flexible are established based on finite element analysis, stability simulations experiments also performed. Simulation experiment results show type have important influence system, instabilities coupled through caused oil whirl or oscillation. result indicates instability rotor-gear coupling-bearing system induced oscillation, however, implies that the self-oscillation which...
In this paper, numerical and experimental investigations are presented on the hydrodynamic performance of a horizontal tidal current turbine (TCT) designed made by our Dalian University Technology (DUT) research group. Thus, it is given acronym: DUTTCT. An open-source computational fluid dynamics (CFD) solver, called pimpledymfoam, employed to perform simulations for design analysis, while tests conducted in DUT towing tank. The important factors, including self-starting velocity, tip speed...
The orifice type radial aerostatic bearing was taken as the subject. flow field under different eccentricity and rotation speed calculated with three-dimension method. influence of types on characteristics bearings analyzed high-speed working conditions. For orifice-compensated type, installation them their also discussed. results indicate when is big, have a bigger main gas film stiffness smaller cross because dynamic effect. consumption than that orifice-restricted same supply hole...
