柠条是内蒙古地区主要的防风固沙植被，种植区域广、面积大。柠条平茬、收获对收获机的需求量大。针对传统柠条收获机油耗高、污染重的问题，以课题组设计的增程式混合动力柠条收获机的最高车速、最大爬坡度和纯电动续驶里程为目标函数进行动力参数设计。首先依据整机设计参数及性能需求，进行了收获机增程器、驱动电机、电池的参数设计。结合实际作业工作参数运用AVL/Cruise软件进行仿真，寻找整机性能指标的最优解。通过整机现场试验验证仿真结果的合理性，对比二者结果知：最高车速的误差为9.012%，爬坡度误差为6.404%；两种结果误差在允许范围内。研究表明仿真模型的合理性，可为后续增程式混合动力柠条收获机动力参数优化提供参考。

Caragana is the main wind-breaking and sand-fixing vegetation in Inner Mongolia, with a wide planting area and a large area. There is a great demand for harvesting machine in the stubble and harvesting of caragana. Aiming at the problems of high fuel consumption and heavy pollution of traditional caragana harvester, the maximum speed, maximum gradient and pure electric driving range of the extended range hybrid caragana harvester designed by our research group were used as the objective functions to design the dynamic parameters. Firstly, according to the design parameters and performance requirements of the whole machine, the parameters of the range extender, drive motor and battery of the harvester were designed. Combined with the actual working parameters, AVL/Cruise software was used to simulate and find the optimal solution of the overall performance index. Combined with the actual working parameters, AVL/Cruise software was used to simulate and find the optimal solution of the overall performance index. The reasonableness of the simulation results is verified by the field test of the whole machine. Comparing the two results, it is found that the error of the maximum speed is 9.012% and the climbing error is 6.404%. The error of the two results is within the allowable range. The results show that the simulation model is reasonable and can provide reference for the optimization of dynamic parameters of the extended range hybrid Caragana harvester.
