This paper proposes to use the principle of "Superharmonic Resonance" in theory of nonlinear vibration to explain a common frequency peak phenomenon in field tests of metro environmental vibration. Based on the theory of FMBD (Flexible Multi-Body Dynamics), a complex “vehicle-track-tunnel” model was constructed with help of Universal Mechanism soft...
Based on the large general multi-body dynamics simulation and analysis platform Universal Mechanism( UM) ，a professional computer program UM Maglev is developed for the coupling vibration simulation of maglev train-track beam． The maglev train is set as multi-rigid-body model，the stiffness and damping of springs and dampers are regarded as linear o...
A subway track detecting vehicle, whose trail bogie is equipped with a detector frame is studied in this paper. The hinged detector frame brings a super constraint problem which leads the integration difficulty of the MBS model. The solution is to substitute a flexible body for the rigid detector frame. An equivalent model, in which the bushing for...
The aim of the paper is to present the approach for simulation of dynamics of the systems consisting of railway vehicle, flexible track and flexible foundation. Railway vehicles are considered as multibody systems that include rigid or flexible bodies, joints and force elements. The track model is considered as a periodic 3D structure consisting of...
A massless track-wheel-terrain interaction model for the real-time simulation of tracked vehicles is suggested. The model is oriented for simulation of tracked vehicles on highly non-smooth urban and industrial terrains that include such elements like stairs, vertical obstacles etc. The suggested model provides realistic tracked vehicle dynamics an...
The paper includes a formulation of algorithms for parallel generation and numerical solution of equations of motion of multibody systems. Replacing rigid joint by compliant ones, use of analytic expressions for Jacobian matrices of stiff forces, implementation of the conjugate gradient method with a proper block-diagonal preconditioning matrix for...
