摘　　要：为了提高装载机能源的利用率和变矩传动效率,通过分析某5t装载机的工况特点,提出了重度串联式油电混合动力方案。针对该方案提出模糊逻辑控制策略,通过在线估计系统需求转矩,以需求转矩和超级电容SOC值作为输入,得到发动机、发电机及电动机的输出转矩。结果表明:超级电容SOC值变化稳定,发动机输出转矩基本处于高效区,比传统装载机节油约16.6%,改善了燃油经济性。In order to improve the utilization of energy and the variable torque transmission efficiency of loaders, a full series hybrid scheme is proposed based on the analysis of the working condition of a 5 t loader. A fuzzy logic control strategy regarding to this scheme is developed. By this control strategy the system required torque can be online estimated; then, taking the required torque and the SOC value of the super capacitor as the inputs, the output torques of the engine, the generator and the motor can be achieved. Results show that the SOC value of the super capacitor is stable, the engine output torque basically falls the high efficiency zone, which can save about 16. 6% fuel than the conventional loaders, so this strategy can improve the fuel economy.
