MATHEMATICAL MODEL OF DIESEL LOCOMOTIVE LUBRICATION SYSTEM
A mathematical model of a locomotive diesel engine lubrication system is proposed, which provides the possibility of forming training samples for reference diagnostic models of the system. A feature of the developed model is an analytical description of the work of the crankshaft main and connecting rod bearings, while a common solution is the use of the hydraulic characteristic of the diesel engine as a whole as one of the elements of the network. Despite a number of assumptions made by the authors that simplify the calculation, the model adequately reflects the change in the controlled parameters of the diesel lubrication system in various modes of its operation under different technical conditions of the system units, which allows using the results of this work to solve a wide range of problems related to the control of the technical condition of diesel engines.
