一种变速器参数优化匹配方法研究
Research on a novel method for transmission parameters optimal matching
摘要
Abstract
For both the improvement of the performance and fuel economy of vehicles,the multi-goal optimal matching design for transmission ratios are carried out.In order to solve the optimization problem effectively,using the weight method to obtain dynamic performance optimal objective function from the vehicle peak speed,0～ 60 km · h-1 acceleration time and peak slope on 1 st gear,as well as taking the fuel consumption per 100 km as the economic optimal objective function,and then to obtain Parato solution set of this multi-objective optimal problem based on the multi-island genetic algorithm.The optimal results showed that the overall performance of the vehicle has been improved,and the optimal method can be applied to solve the powertrain parameters matching design problem.关键词
