Virtual Reality and Distributed Simulation are two pop technologies used in military training and simulation. Routine way to implement an HLA application is by calling RTI APIs, but it is always fussy and fallible. In this paper, VR Link is taken as a development tool for HLA and Vega is chosen as a graphic engine. The flow chart and the implementation of the HLA-based training application are described in detail. Result of operational experiments shows that this is an easy, vivid and effective way for the realization of Distributed Interactive Simulation.

Proposed wheeled off-road excavator with 2-Dof articulated body, and analyzed the working principle of the 2-Dof articulated body, machine-hydraulic drive system and the key technologies .Through the study of the vehicle drive system matching calculation and the ADAMS simulation of articulated body, the results show that the articulated truck has good passing ability, stability and adaptability on a complex road.

Detailed analysis of the mechanism of truck crane, establishes a co-simulation model of the telescopic system with the software of AMESim and Virtual.Lab motion, and conducts a serious of experiments. The performance of Truck crane telescopic system is learned through the comparative analysis of the simulations and experiments. The result shows that this co-simulation can simulate the actual work of the telescopic system well.
