中文摘要:定性分析了六轮独立电驱动、并联运行铰接车不同行驶状态下无跟随控制的整车功率流状态。建立了系统功率流模型和轮边电动机功率矩阵,采用功率键合图法和归一化功率矩阵描述了系统功率流。试验以转矩为调节目标,采用调压的方式模拟永磁同步电动机并联运行的功率流状态。试验分析表明直线行驶和电制动时两侧轮电机牵引和制动功率分配均衡;转角较大时外侧轮电动机再生发电并产生制动转矩,内侧轮电机负荷加重,滑转率增大,轮速比系数kn随着转向角的增大而增大,功率比系数kP随之减小,载荷大小对kn的影响不大,转矩比系数kT为后桥大于前桥且重载大于轻载;打滑轮电动机转速增大而转矩减小,行驶稳定性变差。

Abstract:The qualitative analysis of system power flow was made for articulated vehicle which had six independently-electric-driving wheels running in parallel under different driving states without following control. The system power flow model and wheel-motor power matrix were established. System power flow was described by using power bond graph and normalized power matrix. Taking torque as the control target, the test was performed to simulate the power flow state of permanent magnet synchronous motors running in parallel by means of adjusting voltage. Test analysis showed that the traction and braking power of the wheel-motor on both sides were equal when driving and electric braking straightly. The outside wheel-motors ran into regeneration state and produced braking torque when steering angle was large, then inside wheel-motors’ load were aggravating and theirs slip ratio increased. Speed ratio kn increased with the increasing of steering angle, but power ratio kP decreased at the same time. The severity of load had little effect on kn, Torque ratio kT of the rear axle was larger than the front axle and overload state was larger than light load state. 

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.
