中文摘要:研究了装备电控机械式自动变速器车辆的起步过程。基于实车传动系各主要部件的惯量、刚度、阻尼等扭振参数,建立了六自由度车辆传动系动力学模型,在考虑变摩擦因数和干式离合器从动盘波形弹簧非线性压缩特性的条件下,根据加速踏板开度分别控制节气门开度变化率和离合器压盘接合行程量及接合速度,维持发动机恒转速起步。通过仿真,验证了该起步控制方法的可行性,得到了考虑传动系扭振因素的起步过程离合器传递转矩与冲击度,仿真结果更加接近于实际情况。

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.
