Purpose The purpose of this paper is to realize the lightweight of connecting rod and meet the requirements of low energy consumption and vibration. Based on the structural design of the original connecting rod, the finite element analysis was conducted to reduce the weight and increase the natural frequencies, so as to reduce materials consumption and improve the energy efficiency of internal combustion engine. Design/methodology/approach The finite element analysis, structural optimization design and topology optimization of the connecting rod are applied. Efficient hybrid method is deployed: static and modal analysis; and structure re-design of the connecting rod based on topology optimization. Findings After the optimization of the connecting rod, the weight is reduced from 1.7907 to 1.4875 kg, with a reduction of 16.93%. The maximum equivalent stress of the optimized connecting rod is 183.97 MPa and that of the original structure is 217.18 MPa, with the reduction of 15.62%. The first, second and third natural frequencies of the optimized connecting rod are increased by 8.89%, 8.85% and 11.09%, respectively. Through the finite element analysis and based on the lightweight, the maximum equivalent stress is reduced and the low-order natural frequency is increased. Originality/value This paper presents an optimization method on the connecting rod structure. Based on the statics and modal analysis of the connecting rod and combined with the topology optimization, the size of the connecting rod is improved, and the static and dynamic characteristics of the optimized connecting rod are improved.

According to the plunger pump movement principle, this paper analyzed the two kind of typical force situation of the connecting rod, and obtained the theoretical maximum value of the force. The finite element analysis method was applied to analyze the structure strength of the connecting rod. The finite element model of the connecting rod was established, and the load handling and boundary condition was analyzed. The maximum stress 405MPa occurs at the transition from the small end to the link body. The average stress of the link body is 136MPa. The maximum displacement is 0.17mm, belongs to the small deformation range. The last results of the node stress and displacement show that the connecting rod can work safely.

The Finite Element Analysis

Since it is too complex to make the engine connecting rod design digital and too amount of work to make mistakes, a method based on the CATIA to achieve the engine connecting rod digital design is proposed. Firstly, the parameterized modeling of connecting rod is completed based on secondary development of CATIA. And then, the finite element analysis is applied to the model. Finally, the analysis results verify the effectiveness of the proposed method.
