Adopting the contact finite element method, with complex connecting rod group assembled body model of computation, the fatigue strength of the connecting rod of a certain type of diesel engine was verified. A transient stress analysis was conducted on the connecting rod. Compared with the connecting rod static stretching and compression test, the contact finite element method, which was used to analyze the strength of the connecting rod subassembly, was feasible. Based on the contact finite element method, the connecting rod transient stress analysis results showed that the maximum stress of the connecting rod did not occur under the highest pressure of the cylinder, and the dynamic stress value was greater than the static stress value.

Element Method

Connecting rod fatigue in a certain type of diesel engine is analyzed by using finite element analysis method and the FEM software ANSYS. According the actual working conditions, the three-dimensional model with multi-body contact is established to simulate the contact between the connecting rod parts; By using APDL language programming, the work load on the connecting rod, calculated according all the link work loads, is applied to the connecting rod bearing and bushing through the oil film pressure distribution. By finite element method structural strength of the connecting rod was calculated, that can effectively guide the connecting rod design, which has been proved by practice.

Stress analysis was performed for certain connecting rod assembly by the finite element method, exploring the influence of connecting rod strength with the change of interference. After calculation, it was found that the stress in oil hole of connecting rod small end and bottom edge in the inner hole of connecting rod small end was large. Through the comparison of the different scheme, it got that : the change of the interference of connecting rod small end bushing had a great effect on the stress in oil hole and bottom edge. The increasing of interference made the stress of the bottom edge in the inner hole increase gradually and basically linearly; The maximum stress of oil hole decreased at first, and then increased. Without considering interference, maximum stress was 117MPa. When the interference was 0.01mm, maximum stress got the minimum value about 96MPa. After it, with the increasing of interference, maximum stress increased gradually. When the interference is relatively small, the breakout pressure plays a key role in the stress of oil hole of connecting rod small end, and when the interference is relatively large, the interference plays the leading role.
