摘要
以汽车传动系统优化设计的数学模型为研究对象。分析出在目标函数加权因子的确定时,为了保证加权因子能够客观反映对应分量的权重,应对目标函数分量做归一化处理。运用MATLAB遗传算法工具箱优化了客车传动系参数。结果表明:在汽车动力性、经济性参数优化问题上,并行、非线和高效的遗传算法是一种有效的手段,能使车辆在保证动力性的同时提高经济性。
Mathematical mode designed for automobile transmission optimization is analyzed. When weighting factor of objectivefunction is targeted, objective function components should be normalized to ensure that the weighted factor can objectively reflect the weightof the corresponding component. MATLAB genetic algorithm toolbox is used to optimize parameters of automobile transmission. The resultsshow that genetic algorithm is parallel, nonlinear and highly efficient. It is effective for parameters optimization of automobile powerperformance and its economy. After the optimization, vehicles can be more economical if dynamic quality is guaranteed.
