The Finite Element Model

In this paper, the clamping unit of a two-platen injection molding machine was modeled by Pro/ENGINEER, and was imported to Altair HyperWorks. In HyperMesh module, the finite element model was set up, ANSYS has been used in the finite element analysis of the clamping unit and the deformation and stress results were obtained. Based on the topology optimization of HyperWorks/OptiStruct, recommendations to improve the structure of the clamping mechanism are presented; the results showed that less material was used while its performance was maintained.

The Finite Element Model

Create the finite element model of the frame in ANSYS, and then apply the corresponding boundary conditions and loads for static analysis under the two typical operating conditions of the bending and twisting. And then identify the part suffered a relatively bigger stress in the frame by analyzing the results to verify whether it meets the requirements of its strength. Finally, make a preliminary topology optimization for the frame

Maximum Equivalent Stress

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.
