“…Hollomon-type flow rules are used in these FV simulations for each of the three material types employed: N0, N2 and N2 with flash treatment. To this end, different isothermal compression tests are performed [26]. As may be observed in Figure 11, the prediction of the maximum required force is precise both in the first and in the second stroke, although the shape for the load-stroke curve of the second stroke does not fit very well due to the different initial positioning in the FV simulations.…”

“…In this case, it is very important to evaluate the fatigue behavior and the possible buckling. Moreover, studies on different methods to decrease the friction coefficient between the connecting rod heads and the shaft are found in the bibliography [25], as well as redesigns in order to improve the fatigue behavior by reducing the contact pressure of the heads with the shaft [26].…”

Over these last few years, there has been a growing interest in developing mechanical components from submicrometric materials due to the significant improvement that these materials present compared to their original state. This present research work deals with the study of the mechanical properties of a connecting rod isothermally forged from different starting materials. These materials are as follows: annealed aluminum alloy (AA) 5754, the same alloy previously deformed through equal channel angular pressing (ECAP) and a third case where the previously ECAP-processed material is subjected to a recovery heat treatment. A comparison is made between finite volume (FV) simulations and experimental tests with respect to hardness, plastic strain and forging force. Furthermore, the improvement in the mechanical properties of the connecting rod forged from predeformed material is evaluated in comparison to the connecting rod forged with annealed material. The microstructure of both cases is also compared at the end of the manufacturing process.

“…The CR experiences various forces of piston acceleration and deceleration from the stroking motion, loads generated by friction and the load by the cylinder pressure during the combustion stroke. Under normal operating condition, the design of the CR for infinite number of cycles is based on these forces such that designed CR does not exceed the desired strength during the life span [1][2][3]. If it is not strong enough, fatigue failure of the CR would occur, thereby leading to component fracture and engine failure.…”

Abstract:The connecting rod (CR) is the main moving parts and an important component of engine. If the reliability is not strong enough, fatigue failure of the CR would occur, thereby leading to component fracture and engine failure. So much so that CR fracture. It will lead to engine fault as well as serious outcome. In this paper, stress distribution and fatigue life of CR in light vehicle engine were analyzed using the commercial 3D finite element software, ANSYS TM . The results showed that the medial surface of small end will be the critical surface whereby damage will initiate at the maximum stretch condition. The maximum stress and deformation values are 190.23 MPa and 0.0507mm respectively. The critical location is at the transition region between the big end and connecting shank at maximum compression condition. The maximum stress and deformation values are 459.21 MPa and 0.0702283 mm respectively. Safety factor is 1.584. In order to increase the reliability of CR, some improvement is carried out. Safety factor of CR increases by 59%.
