Abstract

The invention discloses a finite-element-based crankshaft stress analysis method. The problem that in the prior art, analysis of a crankshaft is not suitable for an enterprise is solved. The method has the advantages of being high in practicability, high in accuracy and capable of verifying the fatigue strength of the crankshaft through static analysis. According to the technical scheme, a crankshaft three-dimensional model is established; a crankshaft belt oil hole single-throw model, a crankshaft single-throw simplified model and a crankshaft integral model serve as static analysis models, and static analysis is conducted on the crankshaft; the three models are compared and analyzed, and the optimal model is selected; the crankshaft is subjected to kinetic analysis; a crankshaft modal test is carried out, and an analysis result is checked; the crankshaft is optimized, and post-optimization crankshaft static analysis and kinetic analysis are carried out.

Description

technical field [0001] The invention relates to the field of engines, in particular to a finite element-based crankshaft stress analysis method. Background technique [0002] With the development of modern industrial technology, various new technologies and new research are applied to the design process of the engine, and the emission standards are becoming more and more stringent. The engine is gradually moving towards high speed, high power, low fuel consumption, and low emission. development in a new direction. However, in general, the increase in power will bring many negative effects to the engine. When the power increases, the maximum burst pressure of the piston will increase, which will cause the mechanical load on the diameter of the crankshaft connecting rod to increase, which may cause damage to the crankshaft. . It may also cause the cylinder gas pressure rise rate to be too large, which will cause knocking, increase the combustion noise of the engine, and redu...
