中文摘要:为了使定量泵输出多级定流量以及不用减压阀为多个不同压力系统提供能源,设计并试验了双定子泵,并在此基础上提出了多泵单马达传动理论。以双作用双定子泵和斜盘式轴向柱塞马达组成的多泵单马达传动系统为例,分析了多泵在不同的工作方式下输出波动性不同的油液对马达输出转矩的影响。结果表明,多泵在不同的工作方式下对系统输出特性的影响不同,且内、外泵联合工作时,马达输出转矩品质优于内、外泵单独工作;当泵和马达波动周期一致时,可以合理调整滞后角使马达输出转矩更平稳。为了验证理论分析的正确性,搭建了多泵单马达传动系统试验平台,采集相关数据并描绘出多泵在不同工作方式下马达输出转矩的不均匀系数变化曲线。试验结果和理论分析一致,证明了理论分析的正确性。

Abstract:In order to make constant displacement pumps output multi-level constant flows and provide energy for several different pressure systems without a reducing valve, a double-stator multi-pump was successfully designed and tested, and the transmission theory was also presented. Taking the multi-pump and single-motor transmission system which consists of double-stator double-acting multi-pump and swash plate type axial piston motor for example, the influence of different volatilities of fluid output by multi-pump in different working ways on the motor output torque was analyzed. The results show that the effects of multi-pump on the system output characteristics were different in different working ways. When the inside pump and outside pump were working together, the motor output torque was superior to when they were working alone. When the fluctuation cycles of pump and motor were consistent, the motor output torque could be more stable by adjusting the lag angle reasonably. For verifying the correctness of the proposed theoretical analysis, the experimental platform of multi-pump and single-motor driving system was built, and the relevant data were collected to depict the diagram of uniformity coefficient of motor output torque in different working ways. The experimental result was consistent with the theoretical analysis, which showed the correctness of theoretical analysis.

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.
