客车的CRUISE动力传动系统仿真模型评价分析

Evaluation Analysis of Drivetrain Simulation Model of Bus Established via CRUISE

客车动力传动系统参数的匹配是客车的关键设计内容之一,主要包括发动机、变速器,主减速器之间的组合,不同的组合会有不同的动力性和燃油经济性。通过CRUISE仿真软件建立了客车整车的动力传动系统仿真模型,模拟计算出客车的动力性和燃油经济性指标值,同时依据国标对客车进行了道路试验,测得客车在实际道路的动力性和燃油经济性指标值,对比模拟计算和试验值,验证了CRUISE所建立的客车仿真模型是可靠的,且具有较高精度。

The bus drivetrain parameter matching, one of the key design projects of buses, mainly involves the combinations among engine, transmission,and final drive.Different combinations may generate different power performances and fuel economies.In this paper,the bus drivetrain simulation model was established via CRUISE simulation software,and the index values of bus power performance and fuel economy were calculated.Secondly,the bus road test was completed according to national standard to produce the values of power performance and fuel economy on actual roads.The simulated values and tested values were compared with each other, and the results proved the reliability and precision of the bus simulation model established via CRUISE.
