Stiffness and Mode Analysis of Framework for an Aerial Inertial Stabilized Platform

Abstract In the framework structure design of an aerial inertial stabilized platform (AISP), simulation software was used to analyze its stiffness and vibration mode. Its stress and strain distributions and modal characteristics under a large load were obtained. Then, according to the analysis results, its structure optimization design was implemented to meet the requirements of AISP in control precision. The results of optimized analysis showed that the rigidity of optimized frame structure was significantly improved, while its dynamic characteristics were also effectively improved. Therefore, it verified the necessity and feasibility of engineering analysis for the platform structure design, and it could provide a theoretical basis for AISP design.
