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.

This paper has introduced the finite element analysis (FEA) into the ergonomic design to evaluate the human feelings numerically and objectively, and then into the optimization design of beverage containers considering human factors. In the design of the end of can (the lid of can), experiments and the FEA of indenting vertically the fingertip pulp by a probe and the tab of end have been done to observe force responses and to study feelings in the fingertip. A numerical simulation of finger lifting the tab for opening the can has also been performed, and discomfort in the fingertip has been evaluated numerically to present the finger-accessibility of the tab. The comparison of finger-accessibility between two kinds of tab ring shape designs showed that the tab that may have a larger contact area with the finger is better. In the design of beverage bottles served hot drinks, the FEA of tactile sensation of heat has been performed to evaluate numerically the touch feeling of the finger when holding the hot bottle. The numerical simulations of embossing process have also been performed to evaluate the formability of various rib-shape designs. The optimum design has then been done considering the hot touch feeling as well as the metal sheet formability.

The Finite Element Analysis

A Compliant XY micropositioning stage is purported for situating a material sample in nanoindentation tester process. This paper aims to develop, analyze and optimize a XY compliant micropositioning stage. The working stroke of proposed XY stage is amplified by combining the four-lever and a bridge amplification mechanism. To enhance the performances of the stage, the main geometric parameters are optimized by an integration method of Taguchi method, response surface method (RSM) and genetic algorithm (GA). Firstly, static analysis and dynamic analysis are conducted by the finite element analysis in order to predict initial performances of the XY stage. Secondly, the number of experiments and the data are retrieved by combination of the finite element analysis-integrated Taguchi method. Thirdly, the effects of main design variables on the output response sensitivity are considered. Later on, mathematical model for the amplification ratio was established by the RSM. Finally, based on the mathematical equation, the GA is adopted to define the optimal design variables. The results of numerical validations are in a good agreement with the predicted results. The results depicted that the proposed hybrid approach ensures a high reliability for engineering optimization problems.

The finite element model of a 0201 V-shaped, U-shaped, and UV-shaped single corrugated board corrugated boxes are established. The stress distribution and strain of the three types of waveform corrugated box to withstand the pressure of the top surface stacking are calculated. Three kinds of corrugated board compression are analyzed. Analysis of the structure shows that the V-shaped corrugated board has good rigidity, U-type corrugated box has good cushioning properties, and the range during which the UV type is a better choice. This is consistent with the experimental results, prove the validity of the finite element analysis, and provide data basis for optimization design of the shape of the corrugated board corrugated waveform.
