摘要：本文针对国产12V190燃气机连杆出现的断裂现象,结合连杆实际工作条件,采用有限元软件ANSYS进行应力分析,确定了连杆的最大应力部位。通过与现场连杆断裂位置比对,验证了连杆在结构设计上是安全可靠的。文中的连杆断口分析也验证了这一点。

Abstract: This article in response to the
fracture phenomenon of 12V190 domestic gas engine connecting rod,combined with
its actual working conditions,using finite element software ANSYS for stress
analysis of connecting rod to determine the linkage position of maximum
stress.Through the connecting rod on-site fault location than the right,this
article verified the link in the structural design is reliable.Text of the
connecting rod fracture analysis also verified this point.
Keywords: Gas Engine;Connecting Rod;Finite
