中文摘要:为了实现互联悬架的能量回收及性能优化,提出了一种液压互联式馈能悬架。结合反向互联悬架的结构特性,研究了该悬架的馈能机理。建立四自由度半车辆悬架系统动力学模型,并在AMEsim/Simulink联合仿真环境下,对车辆动力学性能及馈能效果进行了仿真分析,运用Isight的遗传算法对悬架弹簧刚度和液压缸缸径进行了优化求解。在仿真基础上,进行了台架实验,结果表明理论研究与实验结果较为吻合,验证了所提出的液压互联式馈能悬架仿真模型的正确性以及馈能理论的有效性。

Abstract:In order to meet the energy recovery and performance optimization of hydraulically interconnected suspension, a hydraulically interconnected energy-regenerative suspension was proposed. Combined with the structural characteristics of the reverse interconnected suspension, the energy-regenerative mechanism was introduced, and the dynamic model of a 4-DOF vehicle suspension was established. The vehicle dynamic performance and the energy-regenerative effect were simulated by using the joint simulation AMEsim/Simulink. The α-method was used to calculate the weight coefficient of evaluation indexes. The parameters of the spring stiffness and hydraulic cylinder diameter were extracted from eight potential parameters by means of design of experiment to perform optimization with genetic algorithm in Isight. Both vehicle dynamic performance and energy-regenerative effect were optimized. Based on simulative computation, the bench test of full vehicle was carried out under linear condition on a random road using the 4-poster road simulator. The results showed that the vehicle dynamic performance of the new suspension was slightly worse than that of the traditional interconnected suspension, but it can meet the most road conditions and recover part of vibration energy under the premise of maintaining 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.
