Motion Characteristic Simulation Analysis of Suspension System of Forest Fire Patrolling and Fire-fighting Vehicle

The forest fire patrolling and fire-fighting vehicle suspension system is a multi-body system, whose components movement relations are relatively complicated. It is difficult to use design technique and traditional computation method to analyse all kinds of motion characteristic of that suspension system. The front suspension of the forest fire patrolling and fire-fighting vehicle is mainly investigated in this paper. The three-dimensional visual model of the suspension system of the vehicle, carrying on motion characteristic simulation test, is set up using the ADAMS/Car (Automatic Dynamic Analysis of Mechanical Systems)software. Test results show that the motion characteristic simulation analysis of the suspension plays an exemplifying and guiding role on actual production, simulates actual environment efficiently, decreases test times of physical prototyping, and reduces the development cost greatly.
