Assembly design and research of spatial multi-joint array spreading and collecting linkage mechanism

In order to improve the synchronization, accuracy and assembly efficiency of the spatial multi-joint array spreading and retracting mechanism, this study takes the spatial multi-joint array spreading and collecting linkage mechanism of a radar as the research object, and carries out detailed design of the assembly method and sequence of the spatial multi-joint array spreading and collecting linkage mechanism, and analyzes and measures the accuracy, deformation and synchronization of the spreading and collecting linkage mechanism after the assembly is completed. The results show that the designed assembly method has higher assembly efficiency, good synchronization, repeatability and reliability, and the root-mean-square value of array accuracy is as high as 1.43mm, which meets the design requirements. This study provides a strong guarantee for the subsequent design and batch production of radar arrays using similar spatial multi-joint spreading and collecting linkage mechanism.
