The virtual prototyping technology in corporation with a finite element analysis was first used to analyze the strength and stiffness of gearbox casing in an electric bus. On the basis of this analysis, the topology optimization technology (TOT) based on the variable density method was introduced into the design of gearbox casing which takes the minimized total flexibility of gearbox as the objective function, the density of each cell as the design variable and the volume as the design constraint. Then, according to the results of topology optimization and the requirements of manufacturing process, the structure of gearbox casing was designed in detail. Finally, the stress analysis of the housing model of the final design was carried out. The results show that the optimized housing not only meets the design requirements of stiffness and strength, but also reduces its quality, which can make the performance of gearbox achieve optimal.

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.
