Based on virtual prototype technology, combined with three-dimensional modeling, FEA and multi-body dynamics software, simulation technology of tracked vehicle ride comfort was studied. A mixed rigid-flexible virtual prototype of a certain tracked vehicle and a random uneven road were created to form the simulation system of ride comfort. The ride comfort simulation was carried out on the F-level virtual road, from which the acceleration curves at the location of driver were captured. According to the evaluation standards, the ride comfort of the tracked vehicle was analyzed and evaluated. By compared with the actual tests and computing results, it shows that the simulation model system and evaluation method are reasonable and feasible for analyzing and improving the mobility of tracked vehicle.
