Design and Performance Analysis of Efficient Semi-active Energy-Regenerative Suspension

    摘要
  • 摘要: 为改善齿轮齿条式馈能悬架的阻尼特性和馈能特性,在普通齿轮齿条式馈能悬架的基础上,采用钕铁硼永磁发电机、变速机构、换向机构和冲击保护装置,设计了高效馈能半主动悬架,并进行了仿真分析和试验研究.与普通齿轮齿条式馈能悬架相比,该高效馈能半主动悬架发电机转子的转动惯量减小71%,体积减小约40%,节省励磁功率20~30 W,死区由-0.22~0.22 m/s减小到-0.04~0.04 m/s,阻尼特性和馈能特性得到改善,能量转换效率由20%左右提高到50%以上;与被动悬架相比,该高效馈能半主动悬架使汽车的轮胎动载荷、簧载质量的垂直加速度和悬架动挠度的最大值均下降20%以上.

     

    Abstract: On the basis of normal gear and rack type suspension, an efficient semi-active energy-regenerative suspension was designed to improve the damping properties and energy-regenerative characteristics of gear and rack type suspension. This suspension consists of a NdFeB permanent magnet generator, a variable-speed mechanism, a reversing gear and an impact protection device. The simulation and experiment for the efficient semi-active suspension were made. The research results show that compared with the gear and rack type suspension, the rotary inertia and volume of generator rotor of the semi-active energy-regenerative suspension are reduced by 71% and about 40% respectively, exciting power is saved by 20 to 30 W, and dead zone is decreased from -0.22-0.22 m/s to -0.04-0.04 m/s. Furthermore, damping and energy-regenerative characteristics are improved, and energy conversion efficiency raises from about 20% to over 50%. Compared with the passive suspension, the maximum value of dynamic tyre load, the maximum vertical acceleration of sprung mass and suspension dynamic deflection all are decreased by over 20%.
