Abstract
ANSYS finite element software was applied to analysis the stress of connecting rod working in tension and compression conditions to obtain the stress intensity distribution. The result show that the greatest stress is at the inner surface of the connecting rod small end hole and the maximum stress intensity value are 15. 1 Mpa and 161.0 Mpa. Then using the ANSYS finite element software to analysis the reliability of connecting rod and Monte-Carlo method was chosen. According to that obtained the mean probability is 2. 62% when the connecting rod in the 95 % confidence level and initial limit state Z<0(Z =σ, -σma ; in which σmax is the maximum stress occurred during the container used and σ, is yield strength of material). In other words, the reliability of the connecting rod is 97. 38%, and acquire the load distribution histogram and sampling process picture of connecting rod, so it is safe.关键词
