传统的被动悬架具有固定的悬架刚度和阻尼系数,设计的出发点是在满足汽车平顺性和操纵稳定性之间进行折衷。被动悬架在设计和工艺上得到不断改善,实现了低成本、高可靠性的目标,但无法彻底解决平顺性和操纵稳定性之间的矛盾。20世纪50年代产生了主动悬架的概念,这种悬架在不同的使用条件下具有不同的弹簧刚度和减振器阻尼。它能够根据悬架质量的加速度,主动地控制汽车的振动,能同时满足平顺性要求和操纵稳定性要求。自20世纪70年代以来,随着电液控制、计算机技术的发展,传感器、微处理器以及电、液控制元件制造技术的提高以及成本的降低,出现了能够根据汽车行驶的路面、工况和载荷等情况来控制自身工作状态,使汽车的平顺性和操纵稳定性达到最佳的可调节悬架系统。
Traditional passive suspension with a fixed suspension stiffness and damping coefficient, the design is the starting point to meet the car ride comfort and handling stability trade-off between. Passive suspension in the design and process have been continuously improved, to achieve the goal of low cost, high reliability, but can not completely solve the conflict between ride comfort and stability. The concept of active suspension was created in the 1950s with different spring rates and damper damping under different conditions of use. It can automatically control the vibration of the car according to the acceleration of the suspension quality and can meet the requirements of ride comfort and stability. Since the 70s of the 20th century, with the development of electro-hydraulic control and computer technology, the improvement of manufacturing technology of sensors, microprocessors and electric and hydraulic control elements, and the reduction of costs, there have been many problems that can be solved according to the road surface, working conditions and Load and other conditions to control their own working conditions, so that the smoothness of the car and steering stability to achieve the best adjustable suspension system.
