本文提出了一个计算机模拟方法,用以部分地取代城市公共汽车发动机和动力系统其它部分的道路试验。为了使模型更加精确,在华沙市的交通条件下,使用数据记录系统进行了试验。对记录的数据分析表明,所研究的两种城市行驶汽车的模型是具有代表性的;提出了它们的运行模型,并进行了验证。选择发动机和传动系统的最佳匹配作为评价使用性能的标准。介绍了以模型和性能评价为基础的计算程序。最后,本文还介绍了该模拟方法在改善城市公共汽车燃料经济性和动力性方面的应用。
This paper presents a computer simulation method to partially replace road tests of urban bus engines and other parts of the powertrain. In order to make the model more accurate, the data recording system was used under the conditions of traffic in Warsaw. The data analysis of the records shows that the models of the two types of urban driving vehicles studied are typical; their operation models are proposed and validated. Select the best match engine and transmission system as a standard to evaluate the performance. The calculation program based on model and performance evaluation is introduced. Finally, this article also introduces the application of this simulation method in improving the economy and power of city bus fuel.
