In this paper, a detailed rigid-flexible coupling multi-body dynamic model of heavy vehicle was established using multi-body dynamics method, and B class road model was built using harmonic superposition method. Then, the platform of heavy vehicle dynamics simulation was established. The driver seat acceleration and tire dynamic load were simulated at different speeds under the input of different random road excitations. According to the ride comfort evaluation method provided by ISO2631-1, total weighted root-mean-square (RMS) acceleration evaluation method was used to evaluate the ride comfort of heavy vehicle at different ride speeds.

Taking example of a four-cylinder inline diesel engine that used in vehicle, this paper makes an assembly engine of three-dimensional that based on virtual prototype technology. While using the flexible-body dynamics simulation, the main bearing load that effect engine’s vibration will be gained. And the key point vibration response will be gained when the support part constrained. The experimental results coincide with the simulation results shows the correction of the simulation analysis. The initial stage of the vibration can be predicted by using the method of multi-body system analysis, and this guide the designer to identify the engine vibration.

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.

Motor drive control is the major study field in the development of lunar rover. Based on the double-closed DC loop adjustable-speed system, a motor drive simulation module using a position recursive PID control algorithm is developed, which is integrated into the multi-body dynamics simulation system, to carry out the whole lunar rover simulation. And the cruise process of lunar rover locomotion in the complex lunar terrain is simulated in a virtual environment.
