Research On Traction Force Optimization Of Passenger Locomotive Based On Locomotive Monitoring Data

With the development of China's transportation industry,the status of railways in transportation has become increasingly prominent.Railway energy economy is also an urgent need to solve.Railway is called "green transport",the development of the railway is conducive to environmental protection,the deteriorating energy,environmental issues of great significance.At present,the use of low efficiency,serious waste phenomenon still exists,to strengthen the management of locomotives,improve the use of capacity is an urgent need to solve the problem.Research and analysis of locomotive traction is an important indicator of energy efficiency in rail transport.Analysis of locomotive traction on the use of locomotives,maintenance,optimization of locomotive performance guidance.Therefore,this paper takes the three-tree locomotive station as an example to try to study the utilization of locomotive traction using locomotive monitoring data(LKJ).This paper introduces the research status of locomotive traction at home and abroad,the basic concept of locomotive traction,analyzes the practical application effect of traction force utilization factor and collecting a large number of monitoring data,the basic data are preliminary processing,draw a column chart and line graph of horizontal analysis with locomotive monitoring data intuitively,puts forward optimization suggestions.The specific statistics and analysis of each section are carried out,and the LKJ monitoring data are used to analyze the different lines and the utilization of the traction power of different models.The reason for insufficient traction is analyzed when the DF4 D locomotive traction a fast train.DF11 and DF4 D locomotives in mountainous area are not very high due to their poor traction utilization.To solve the above problems,we should change the different traction locomotive routing,improve locomotive,improve locomotive attachment condition.The use of older locomotives is not only prone to failure,but also a waste of energy and increase costs.For locomotive routing,we should determine the traction type of each train one by one,so that the locomotive with different power and speed grades can be arranged in different levels,so as to minimize the energy waste caused by the "big horse drawn cart".Focusing on the optimization of locomotive traction utilization ratio,this paper makes specific analysis from different locomotive routing,maintenance,selection and design,and puts forward reasonable suggestions for optimization.Taking the optimization of locomotive traction utilization as the key point,the locomotive running condition is analyzed again,which has certain production application value and reduces the cost of railway transportation.It has guiding significance for each locomotive depot and design unit.
