摘要
In order to solve the problems that the existing antenna support mechanisms could not meet the requirements of high load-bearing capacity and large working space simultaneously, a two-rotation and one-translation PM 2RPU-UPR with few joints was proposed to be used as the antenna supporting mechanisms. Firstly, the degrees of freedom of 2RPU-UPR PM with few joints were analyzed and the kinematics model was established. Two optimization indexes, i.e, the maximum load-bearing capacity and motion range of driving branch, were proposed, based on which the key dimensions of the supporting mechanisms were optimized. As a result, a set of structural dimensions that provided excellent performances were obtained. Furthermore, the experimental prototype of the antenna support mechanisms was developed and experimental investisgations were performed. The experimental results show that the proposed antenna supporting mechanisms may withstand large loads, and meet the large working space requirements of ±90° rolling and ±90° pitching, thus it has a good application prospect. © 2019, China Mechanical Engineering Magazine Office.
