中文摘要:为研究半主动悬架车辆行驶平顺性,利用SIMPACK软件建立了整车多体动力学模型,并在半主动悬架七自由度整车行驶动力学模型的基础上,应用Matlab/Simulink软件设计神经网络模型参考自适应控制算法,建立了一个半主动悬架控制策略研究的集成环境,利用该集成环境对磁流变阻尼器的半主动悬架车辆行驶平顺性进行联合仿真。仿真结果表明,与被动悬架相比,当汽车以60km/h和120km/h在C级路面上行驶时,车身垂向、俯仰、侧倾加速度均方根值分别下降了32.33%、28.09%、35.93%和41.56%、18.52%、22.97%。基于神经网络模型参考自适应控制的磁流变半主动悬架可以有效衰减车身的振动,改善车辆的行驶平顺性。

Abstract:In order to study the ride comfort of semi-active vehicle, a detailed multi-body dynamic model of a passenger car was established by using SIMPACK software, and a seven-degree freedom mathematical model for the semi-active automotive system was also built. A model reference adaptive control based on neural network was designed for semi-active suspension system and worked out by means of Matlab/Simulink. The SIMPACK-Matlab co-simulation method was used to analyze the ride comfort of MR-damper semi-active suspension. The result showed that, comparing with passive suspension, when the car is running at 60km/h on grade C road, the neural network controller could reduce the mean square roots of the vertical acceleration, the roll angular acceleration and the pitch angular acceleration by 32.33%, 28.09% and 35.93%. When the speed of car achieved 120km/h, the mean square roots reduced by 41.56%, 18.52% and 22.97%. It is concluded that the model reference adaptive control based on neural network could reduce the vehicle body vibration and improve the ride comfort.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
