In this paper, our aim is to develop a simulation model for Multi-joint demolition water vehicle. 3D model of vehicle is developed with CATIA. The rigid simulation model is built in ADAMS and the flexible simulation models are developed using ADAMS and ANSYS. The combination of the both ADAMS and ANSYS can improve the precision of system simulation. The rigid model with rigid multi-slide booms and rigid refracting booms, the hybrid model with flexible multi-slide booms and rigid refracting booms, and a flexible model with flexible multi-slide booms and flexible refracting booms are considered. The simulation analysis shows a good performance, and valuable results we are interested in are obtained.
