摘 要: | 为分析半主动悬架对汽车性能的影响,文章对半主动悬架的性能进行了仿真分析。首先在ADAMS/View开发环境中建立1/4汽车悬架模型;然后基于MATLAB/Simulink设置模糊控制规则,对半主动悬架进行模糊控制,并模拟出随机路面输入信号;最后利用ADAMS/Control模块将ADAMS和MATLAB/Simulink悬架模型联合起来进行仿真,与被动悬架进行了对比分析.可以看出,模糊控制下的半主动悬架舒适性更高,行驶安全性和操纵稳定性更好。联合仿真结果表明,半主动悬架的舒适性和平顺性均优于被动悬架。

Co-simulation Analysis on Performance of Vehicle Semi-active Suspension |

Abstract: | In order to analyze the inffluence of semi-active suspension (SAS) to vehicle performance, simulation analysis of semi-active suspension is conducted. Establishing quarter suspension model in ADAMS/View software, based on MATLAB/ Simulink, fuzzy logic rules are set to control SAS, and random input signals are simulated. Using ADAMS/Control module, suspension model of ADAMS and MATEAB/Si,nulink are combined and simulated, and comparison analysis with passive- suspension is conducted. It is shown that semi-active suspension has high comfortability in fuzzy control, better riding safety anti control stability. The comhined simulation results indicated semi-active suspension is better than passive-suspension in comfort anti smoothness. |
