摘要：随着不可再生资源的减少，能源问题日渐受到重视，以燃油为动力来源的内燃机车在能耗方面的问题凸显的越来越严重。虽然电力机车在铁路体系中得到了更多的使用，但是在一些偏远地区电力机车无法到达，所以内燃机车仍然扮演着重要角色，因此对对内燃机车能耗系统的研究显得极为重要。本课题主要研究的是内燃机车能耗估算系统，首先进行能耗计算的理论推导，接着使用Matlab编写计算程序以及设计人机交互界面，最后测试运行时分曲线和油耗计算的结果，测试结果显示得到的值和能耗计算推导理论结果相符合。该系统的产生可以实时通过界面将机车的油耗量发送给司机，以便司机优化机车的操作。同时该系统对燃油的监控也对机务段节能减排和降低经济支出有重大帮助。62061

Modeling and Simulation of Energy Consumption for Diesel Locomotive

Abstract：With the reduction of non renewable resources, energy issues have been paid more and more attention to the power source of fuel for diesel vehicles in the energy consumption of the problem is becoming more and more serious. Although electric locomotive in the railway system has been used more, but in some remote areas of electric locomotive can not reach, so diesel locomotive still plays a important role, so the research of diesel locomotive energy consumption system is very important. The main subject of study is diesel locomotive energy consumption estimation system. Firstly, the energy consumption calculation of theoretical derivation and then use matlab to write the calculation program and the design of human-computer interaction interface, test the running time curve and fuel consumption calculation results. The test results show that values obtained and energy consumption calculation theoretical results are in good agreement. The generation of the system can transmit the fuel consumption of the locomotive to the driver in real time so as to optimize the operation of the locomotive. At the same time to monitor the system of fuel depot energy-saving emission reduction and reducing economic expenditure is of great help.
