    摘要:

    首先利用ADAMS軟件建立帶有電動(dòng)助力轉(zhuǎn)向系統(tǒng)(EPS)的整車多體動(dòng)力學(xué)模型;然后在Matlab/Simulink環(huán)境中設(shè)計(jì)了PID控制的EPS系統(tǒng),定義了與ADAMS/CAR環(huán)境下車輛模型的數(shù)據(jù)交換接口;最后,將設(shè)計(jì)的控制系統(tǒng)在ADAMS/CAR和Matlab/Simulink環(huán)境下通過輸入輸出接口進(jìn)行聯(lián)合仿真。幾種行駛工況下的EPS及整車的動(dòng)態(tài)特性計(jì)算結(jié)果,表明聯(lián)合仿真方法是正確有效的,并為其在車輛工程中的實(shí)際應(yīng)用提供了參考。

    Abstract:

    A simulation model with multi-body dynamics and electronic power steering (EPS) was presented based on the co-simulation technology. First, by using automatic dynamic analysis of mechanical systems (ADAMS) software, a multi-body dynamic model of a full vehicle was established, then a PID controller was designed for the EPS under Matlab/Simulink environment; in addition, a data exchange interface with ADAMS/CAR was also defined. At last, a proposed control system including a multi-body vehicle model and a PID controller was implemented by using I/O interface under Matlab/Simulink and ADAMS environment, and the co-simulations have been carried out. The vehicle dynamic response under various operating condition was given. The results showed that co-simulation is effective and it could be applied in the development of vehicle engineering.
