摘要
研究汽车磁流变液流变特性和磁流变液离合器原理,为了提高系统的速度特性、稳定性和调节的自动性能,建立了圆盘型磁流变液离合器传递力矩模型,基于模型设计了适用于小型汽车的磁流变液离合器。建立了基于磁流变液离合器的汽车传动系统动力学模型,采用模糊控制对汽车起步时该离合器的结合过程进行仿真,结果表明:磁流变液离合器的传动力矩够满足小型汽车的传动要求;所设计的磁流变液离合器在起步过程中接合平稳,节气门开度和开度的变化率性能均可满足要求,为设计提供了依据。
Based on the analysis of rheological properties of magnetorheological(MR) fluids's and the structure of MR clutch,the transmission torque model of disc-shaped MR clutch was established.According to this model,the disc-type MR clutch for small car was designed.Based on MR clutch,the mechanics model of automotive transmission system was set up.Using fuzzy control,the performance of automotive MR clutch in automotive starting process was simulated.The results of simulation show that the MR clutch can meet the performance requirements of the small car transmission system;the MR clutch can be joined smoothly with the small impact,and the jointing process can be adjusted automatically according to the opening of throttle valve and the rate of opening.
