Abstract
Topology optimization is performed to reduce material and get the optimum shape of a component that sustains the load transmitted to it. This paper presents the generation and analysis of the optimized design of a bar in the large-sized link mechanism that is used in the radar antenna lifting system. First, the load acting on the bar during antenna lifting is investigated. Next, the most crucial load is applied to the bar under the topology optimization procedure using the SW Ansys Workbench 2021. Based on the finite element analysis using ANSYS, the optimized link mechanism shape is finally modified to achieve the stiffness and strength of the origin requirement. The reduction in initial shape weight achieved is 18.3%. The final link shape is possible to produce using conventional technologies. The article gives the recommendations for further large-sized planer linkages.
