    摘要:

    基于可調阻尼減振器的試驗結果,，擬合了可調阻尼減振器阻尼系數與步進電動機轉角之間的非線性關系,，建立了阻尼非線性半主動懸架數學模型，設計了模糊動態(tài)最優(yōu)控制策略，研制了阻尼非線性半主動懸架系統(tǒng)控制器,，在仿真的基礎上,，進行了實車道路試驗,。結果表明,，阻尼非線性半主動懸架模型更接近實際模型，有效改善了車輛的乘坐舒適性,、行駛安全性,，協(xié)調了整車綜合性能。

    Abstract:

    Based on the test results of tunable damper, the nonlinear relation was fitted between the damping and the angle of the stepping motor. The mathematical model of semi-active suspension with nonlinear damping was built and fuzzy dynamic optimal control strategy was designed. The controller of semi-active suspension with nonlinear damping was developed. On the basis of the simulation, the actual road test has been done. The results showed that the model of semi-active suspension with nonlinear damping was closer to the actual model, the comfort and the security were effectively improved and vehicle performance was coordinated.
