DESIGN AND OPTIMIZATION OF SUPPORT STRUCTURE OF A SENSOR IN SPACECRAFT

In this project, the design and optimization of aerospace brackets and their manufacturing processes was going to be carried out. In the design of aerospace structures, lightweight and high-performance structures were essential because spacecraft often operate in harsh conditions. By Topology optimization, a lightweight aerospace bracket that supports spacecraft sensors was designed which must ensure stiffness, strength and quasi static load requirements. The model of the bracket, we designed should be 3D printed. The additive manufacturing process has evolved dramatically over the past few decades, has found application in many areas, including the aerospace industry where a wide range of material properties was required. Materials should be selected based on it. In spacecraft construction mass reduction was very important. For stiffness requirement, the bracket has to meet the fundamental frequency of >80Hz, when the bracket base was fixed and also the bracket (with sensor) must be able to withstand a quasi-static load of 20g in all directions. In the project, materials with the required properties were selected, as well as design and analysis procedures were carried out in commercial software, to ensure that the design meets the task objectives and results were obtained.
