摘要
提出了基于随机方向法与车辆原地起步加速过程模拟的变速箱挡比优化模型,该模型以变速箱各挡传动比为优化对象,以车辆原地起步加速时间和累积燃油消耗量为目标函数。车辆原地起步加速过程模拟以发动机瞬态工作过程计算为基础。对以涡轮增压柴油机为动力装置、采用闭锁式液力传动的某型装甲履带车辆的变速箱挡比进行了试优化,证明该方法能够为设计及改进车辆动力性和燃油经济性提供参考。
An optimization model for gearbox ratios using the method of random directions and the simulation of acceleration from standing start were proposed. The model takes the gearbox ratios as the object of optimization and takes the acceleration time and accumulated fuel consumption in a standing start acceleration as the optimization target. The model of standing start acceleration for vehicle is based on the transient working process of the engine. Through the results of the example optimization for gearbox ratios of an armored tracked vehicle which uses a turbocharged diesel engine and lockup hydrodynamic transmission, it is proved that this model is helpful in designing and improving the power performance and fuel economy of the vehicle.
