Abstract

The invention provides a fluid coupling analysis method for a connecting rod small end bearing of a diesel engine. The method comprises the steps of building a connecting rod small end basic analysismodel; building a connecting rod small end heat-fluid-solid performance evaluation calculation model; and performing property evaluation on the connecting rod small end bearing. According to the fluidcoupling analysis method for the connecting rod small end bearing of the diesel engine, the process is definite and the operability is high; the calculation problem of uncertain oil supply and temperature field of the connecting rod small end bearing is solved; and a solution of the connecting rod small end bearing in a heat field, impingement cooling and lubricating fluid field and structural deformation field strong coupling system is provided.

Description

technical field [0001] The invention belongs to the technical field of diesel engine design and processing, and in particular relates to a hydraulic coupling analysis method for a small end bearing of a connecting rod. Background technique [0002] The small head bearing of the connecting rod is a special bearing inside the diesel engine, especially for the high-strength diesel engine. It bears a huge mechanical load, a high swing speed, and at the same time bears part of the heat transmitted from the piston to the bearing through the piston pin seat. , so the working conditions are bad, and it is also one of the bearings with frequent failures. Since the working environment of the engine cannot be truly simulated due to the limitation of component test methods, it is necessary to use reasonable simulation analysis methods for effective simulation. [0003] In the early stage of the analysis of the small end bearing of the connecting rod of the diesel engine, the structural...
