Currently, research on the matching of stiffness and damping in the suspension system of wheeled armored vehicles in China mainly relies on empirical and experimental methods. This method is time-consuming and labor-intensive, which prolongs the development cycle of armored vehicles. In order to improve vehicle smoothness and reduce development time, this paper analyzes the influence of suspension stiffness and damping on vehicle acceleration response based on a single wheel two degree of freedom driving vibration model. The general calculation formulas for acceleration, suspension dynamic deflection, and root mean square value of wheel dynamic load are derived. A mathematical model for the optimal damping ratio of the suspension system based on driving safety and comfort is established, and the damping ratio design of a certain type of armored vehicle suspension system is completed. The results indicate that this method can quickly and accurately complete the matching design of suspension system stiffness and damping, reducing the time for vehicle design and development.
