Abstract: The random dynamic responses of the damped gyroscopic system were investigated under random loads. The pseudo-excitation method, as a highly efficient and accurate method for random vibration analysis, had been widely used in the fields of structural seismic and wind engineering. In the Lagrange fra...
Abstract: The Gauss stationary random process was adopted to simulate pavement roughness, and a MATLAB program was compiled to obtain the values of pavement roughness. A 4-DOF vehicle model was built, and the vehicle and road were seen as a holistic coupling system. Then the dynamic equilibrium equations for ...
Abstract: A new method for controlling the macro discrete traffic flow model was presented in the automated freeway system. The non-linear model of traffic flow was transformed to an easily tractable linear system model with the precise state feedback linearization method, and the design of the traffic densit...
Abstract: HLLC is a high resolution scheme, which can capture shock, contact discontinuity and rarefaction wave accurately. But when it is used to calculate multidimensional problems, the phenomenon of numerical shock instability may appear near the strong shock. Compared with the HLLC scheme, the FORCE schem...
Abstract: A general heat transfer model of a parallel plate channel filled with a porous medium was constructed based on the Brinkman-Darcy extended model and the local thermal non-equilibrium model in view of the internal heat sources in fluid and solid phases. The temperature field of the porous medium unde...
Abstract: According to the idea of bionic non-smooth revolution bodies, the SAE (Society of Automobile Engineers) standard model was selected as the object of study, and the computational fluid dynamics (CFD) method was used to investigate the effects of different non-smooth surface dimple array forms and den...
Abstract: The optimization method for the vehicle body assembly structure was studied in view of the overall performance of manufacture and assembly. A modified graph-partitioning algorithm was proposed to optimally divide the vehicle body assembly structure into a set of components. A side frame model for th...
Abstract: It was discovered that the 2 main premises in the proposition of Betti’s reciprocal theorem for 3D linear elasticity, i.e. “1 elastic body” and “action of 2 sets of forces”, were contradictory to each other because either of the 2 sets of forces may change the given elastic body to another one. This...
Abstract: To better describe the temperature-dependent mechanical properties of polymer materials, an improved WLF model was proposed, with a ‘zero time’ factor introduced to promote the precision of the relaxation modulus acquisition at different temperature levels for linearly viscoelastic materials. Therea...
Abstract: The exact traveling wave solutions to a class of 5th-order nonlinear wave equations were studied with the sub-equation method and the dynamic system analysis approach. The lower-order sub-equations of this class of high-order nonlinear equations were first derived, then the traveling wave solutions ...
Abstract: The leader-following consensus of multi-agent systems with fractional-order nonlinear models was investigated. Under the assumption that the system communication topology contains a leader-rooted spanning tree, the control gain matrix was designed and the controllers were presented based on the theo...
