Abstract: The moving vehicle was modeled as a two DOF spring-mass-damper system. The pavement structure was modeled as an elastic beam on a nonlinear viscoelastic foundation. The nonlinear foundation and the road surface roughness were respectively assumed to be cubic and a harmonic function. The nonlinear pa...
Abstract: A closed-loop driver-vehicle-road model with two degrees of freedom (DOF) for a three-axle heavy vehicle was set up. With the influence of the road directional disturbance and driver control considered,the vehicle ordinary differential equations of motion were established. The influences of system p...
Abstract: A nonlinear analysis on a 2D foil subject to wing-in-ground effect (WIG) operating above water waves was made. Through the derivation of the Green’s function for 2D singularities moving above regular water waves, the 2D lifting problem for a foil above water waves was addressed using the discrete vo...
Abstract: In order to study the phenomenon and regular movementpattern of liquid flow in annular space in projects such as oil extraction and drilling,the water hammer problem of liquid flow in annular space,which was rarely addressed at the moment,was discussed. According to the structure characteristics of ...
Abstract: A nonlinear mutual prediction approach was presented to investigate the correlations and coupling strengths of nonlinear dependence among the subsystems in an open complex giant system, which behaved with complicated nonlinear dynamical characteristics. The time-varying discriminant values of mutual...
Abstract: Since the last decade, complex-valued neural networks have been rapidly developed and applied in various research areas, but few research has been done on the periodicity on discrete-time complex-valued neural networks.The periodicity of discrete-time complex-valued neural networks with time-delays ...
Abstract: Oscillatory problems of a class of third order nonlinear delay differential equations were studied. With the techniques of operator and integral, the determinant conditions in which such equations had not A-type solution (or B-type solution) were given. Further, several new sufficient conditions for...
Abstract: The inverse problem of force identification was always ill-posed due to the inverse process of structural matrix and measurement noise in practical engineering and the ordinary least square method usually obtained the meaningless solution, which was called the ill-posed problem of the inverse proble...
Abstract: The wallbounded turbulent flow was simulated directly (DNS) by lattice Boltzmann method (LBM) through multi-GPU parallel computing. The Data-parallel SIMT (single-instruction multiple-thread) characteristic of GPU matched the parallelism of LBM well, which led to high efficiency of GPU on the LBM s...
Abstract: The convective heat transfer performance of internal cooling passage with hemispherical dimples or protrusions was numerically studied and the influence of Coriolis force on heat transfer characteristics in the channel flow was explored. It is found that: the leading edge of the channel shows weak f...
Abstract: Numerical simulations of vortex-induced vibration of a three-dimensional flexible tube under uniform turbulent flow were calculated when Reynolds number was 1.35×104. In order to achieve the vortex-induced vibration, the three-dimensional unsteady, viscous, incompressible Navier-Stokes equation and ...
Abstract: Four calculation methods for numerical simulation analysis of removing temporary supports from large-span steel roof were introduced——support displacement method, equivalent rod bottom-end displacement method, jack element method and jack-gap element method. Then a new method, constraint equation me...
Abstract: The parameter-adjusting method to construct dynamical functions of Birkhoff's equations is put forward based on realizing the completeness of Birkhoff’s equations, which are under-determinate, by means of Cauchy-Kovalevski integrability theorem for partial differential equations. The two kinds of pa...
