摘　　要：在高速工程车设计过程中兼顾其高速行驶和低速作业性能,建立了高速工程车不同工况下的动力性数学模型,编制程序对其动力性指标进行计算。建立动力性目标函数的优化模型,选择整车设计要求作为约束条件,并应用了遗传优化算法,结合实例验证,优化后的高速工程车动力性能较优化前有所改善。Both the ride quality and operational performance are important in the design of high-speed construction vehicle,the mathematical model of power performance was established in different work conditions of the vehicle,and the power performance parameters are computed.The optimization model of the power performance is also established,and the design claim was choosed as the constraint.The genetic algorithm was used in an example and the satisfied result was obtained.

关 键 词：动力性 遗传算法 优化
