英文摘要： With the development of national economy and the improvement of living standard, people pay more and more attention to vehicle performance, thus the research of vehicle suspension system is facing new challenges. Air suspension with its unique advantages attracted wide attention at home and abroad, and has lead the development trend of the future suspension system. Following the latest research trend of air suspension system, this study systematically investigated an air suspension with air damping (air suspension with auxiliary chamber). Based on the existing experimental and theoretical study of the suspension characteristics, further systematic research was conducted to understand the characteristics of the suspension system, and a design method and an effective control method of the suspension system were presented considering various vehicle performances. The main research contents include: establishing mathematical model of the suspension system with design parameters; analyzing the characteristics of the suspension system and its effect on vehicle performance; presenting design method and effective control method of the suspension system based on in-depth study of the connections among suspension design parameters, suspension characteristics and vehicle performance. The purposes of this study were providi
