“…The primary goal of the optimized design of a parallel platform is to establish reliable and computationally efficient performance indexes that affect the final working performance and optimal design efficiency of the parallel platform. The performance indexes of the parallel platform are mainly focused on kinematics (Hamida et al 2021;Nunez et al 2022) (Liu et al 2013).…”

This paper presents a modified Stewart platform that enables precise adjustment of the sub-reflector for the QiTai radio telescope (QTT). QTT demands a parallel platform capable of carrying a heavy load (≥4000kg), and moving in elevation from 5° to 88° together with the primary reflector while precisely adjusting the sub-reflector's position in five degrees of freedom. To meet these requirements, a modified Stewart platform with two actuators bias is proposed, comprehensive performance analyzed and optimized for practical application. The performance of the modified platform is compared to that of the traditional Stewart platform, and the results demonstrate that the modified platform has superior load-bearing capacity and stiffness over the entire elevation angle with more uniform actuator loads and stiffness distribution. These results indicate that the modified Stewart platform is well-suited for practical applications in QTT.
