Based on the multi-body dynamics theory and modal-reduction analysis, finite element method and multi-body dynamics were combined to establish the flexible track model. The rigid-flexible coupled dynamics model can reflect the features of coupled vibration accurately. When the flexibility of the rail, damping and stiffness of support layers under the rail are taken into consideration, the whole track structure acted as a buffer while wheel and rail is interacting with each other. Compared with rigid track model, the wheel-rail vibration is less in the flexible track model. The proposed method in this paper is simple and effective, which makes the calculation of vehicle-track dynamic response more convenient and quick.

This work concerns the implementation of nonlinear modal reduction to flexible multi-body dynamics. Linear elastic theory will lead to instability issues with rotating beamlike structures, due to the neglecting of the membrane-bending coupling on the beam cross-section. During the past decade, considerable efforts have been focused on the derivation of geometric nonlinear formulation based on nodal coordinates. In this work, in order to improve the convergence characteristic and also to reduce the computation time in flexible multi-body dynamics, which is extremely important for complicated large systems, a standard modal reduction procedure based on matrix operation is developed with essential geometric stiffening nonlinearities retained in the equation of motion. The example used in this work is a rotating Euler-Bernoulli beam, two nonlinear reduced models were established based on modal coordinates, the first reduced model created from theoretical bending and axial mode shapes by Galerkin method; the second reduced model is derived by the standard matrix operator from a full finite element model. Transient simulation results of lower degrees of freedom from above two reduced models are compared with those obtained from full nonlinear finite element model.

For the poor ride comfort performance of the articulated dump truck, the dynamic model of ADT was built and its dynamic characteristics were also studied through finite element and multi-body system dynamic theory. According to the modal neutral file generated by finite element software with the flexible processing, the flexible coupling virtual prototyping model was set up for the multi-body dynamics simulation in ADAMS to obtain and analyze the data about the ADT ride comfort. This paper provided references for the design, redesign and optimization of the ADT.

Engine Crankshaft

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as crankshaft acceleration, velocity and displacement by the multi-body dynamics simulation analysis. By calculation, the paper found that by using the combination of finite element and multi-body simulation method, can we effectively simulate the diesel engine crankshaft dynamics characteristics.

For the problem that car sub-frame constraint connection complex and effective load more difficult to determine, using finite element and multi-body dynamics ADAMS co-simulation method, Analyzed on a Volkswagen vehicle sub-frame, obtained the accurate load on the sub-frame which are used by engine suspension. The finite element analysis results show that engine load is the greatest impact on the sub-frame stress field, which can be reduced by increasing the area of engine and the sub-frame contacting, thereby prolong the life of sub-frame.

A new tracked triangular wheel structure was introduced. A whole tracked triangular wheeled vehicle model was built in multi-body dynamics simulation software RecurDyn, and its climbing obstacle performance on the dry soil road was simulated. The author put the simulation results as loading conditions of finite element model. Finite element calculation and lightweight design for tracked triangular wheel base frame were completed. The results showed that the weight of the base frame reduced by 69.8%, the structure properties of the base frame improved, and the lightweight design goal was achieved.
