Lubrication system simulation method and device

Abstract

The invention discloses a lubricating system simulation method and device. The method comprises the steps that fluid system simulation is performed by use of a lubricating system basic model and an input variation range of a lubricating element to obtain workflow of a lubricating system; experimental design calculation is performed on the workflow of the system according to a preset experimental design algorithm to obtain multiple parts of corresponding discrete sample point data of the lubricating element of the lubricating system under each working condition; a continuous surface is fitted on the basis of the discrete sample point data to obtain a response surface model reflecting the functional relation between input parameters and output parameters of the lubricating element; a preset optimal solution algorithm is used for performing optimal solution calculation on the response surface model to obtain ideal input parameters and corresponding ideal output parameters of the lubricating element; and the ideal input parameters and the ideal output parameters are input into fluid system simulation software to obtain a simulation result of the lubricating system. The purposes of reducing lubricating system simulation repetition and improving simulation efficiency are achieved.

Description

technical field [0001] The invention relates to the field of lubrication, in particular to a simulation method and device for a lubrication system. Background technique [0002] Parts that do relative movement in the machine, for example, between the crankshaft journal and bearing of the engine, the camshaft journal and bearing, the piston ring and the cylinder wall, the timing gear pair, etc., will cause the working surface of the part to wear rapidly due to relative movement , thereby increasing power consumption. [0003] The lubricating system is installed in the machine, and by delivering lubricant to the surface of the parts in relative motion, the frictional resistance on the surface of the parts in relative motion can be reduced, and the wear of the parts can be reduced. For example, in an engine, the lubrication system is an important part of it. Through the work of the lubrication system, the surface of the relative moving parts in the engine can be lubricated, r...

Problems solved by technology

[0005] However, manually adjusting the design based on experience and repeatedly simulating to configure the lubrication system not only requires a large amount of calculation, but also the final simulation result may not be an ideal solution, which makes the simulation process of the lubrication system highly repetitive and inefficient
