Results of the studies on the dynamics of three-axial off-road truck, where open load-carrying body was replaced with artillery launcher, were presented. This change resulted in significant increase of carrying system load and changes to vehicle structure were required. On the basis of experimental study results and simulating calculations, new characteristics of elasticity and absorption forces in the suspension of wheels, cabin and crew seats were selected. In the characteristics selection process, special attention was paid to minimise dynamic loads of vehicle carrying system, to limit the effect of lost ground-wheel contact and to limit vehicle vibrations, especially vibrations affecting the crew. Suggested changes to vehicle structure resulted in considerable reduction of dynamic loads affecting the crew of the launcher in different operating conditions. Gained development was evaluated by means of driving comfort indexes, formulated in obligatory standards.
