Abstract:The launch for vehicle equipped automated mechanical transmission was studied. Based on the torsional vibration parameters of vehicle powertrain, such as inertia, stiffness and damp, 6-DOF model of vehicle powertrain was established. Considering the variable friction coefficient and cushion spring nonlinear compression characteristic of clutch driven plate, it controlled the changing rate of throttle opening, engaging displacement and speed according to the opening of acceleration pedal to keep the constant speed of engine while launching. Through the method of simulation, the launching control method with constant engine speed was proved to be feasible. The clutch output torque and jerk value while launching considering torsional vibration factor of powertrain was obtained. The results of simulation were closer to the reality. |
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.
