Abstract:0.8s。 Conventionally, the start-up control strategy of dual mode CVT has focused on obtaining maximum output power of the combination of engine and torque converter; however, this strategy did not pay attention to the efficiency of the metal V-belt unit, which also influenced the start-up characteristics of the system. A start-up control strategy considering both TC and metal V-belt efficiency was proposed. An optimal algorithm was developed to calculate the target CVT ratio in order to obtain maximum driving power with consideration of both TC and metal V-belt efficiency. Simulation and experimental results indicated that, when lock-up speed was 30 km/h and start-up throttle opening was 20%, working time of the TC during the start-up process was reduced by about 0.8 s after the optimization. |
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.
