基于Cruise的客车动力传动系统的匹配研究

动力传动系统的合理匹配与否对客车动力性和燃油经济性的好坏有直接的影响。这里以某客车为例，基于Cruise软件建立该车整车仿真模型并验证模型的准确性。以变速器速比和主减速器速比为匹配变量，利用DOE试验设计方法对适合该客车的两种变速器和五种主减速器进行试验设计组合，然后对组合方案进行动力匹配计算，最后根据相关的约束条件，选出最优匹配方案。

Matching research of bus power transmission system based on Cruise

Reasonable matching of power transmission system has direct effection for bus power and fuel economy.Here take some bus as example,establish simulation model and verify the correction of model based on Cruise software.Consider transmission ratio and final drive ratio as matching variable,using DOE test design method to do experiment design combination for the two kinds of transmission and final drive which are suitable for this bus,and then do power matching calculation for the combination scheme,finally choose an optimal matching scheme according to the relavant constraint conditions.
