Description
To meet the support requirements of a long-span acceleration device, a large-span precision adjustment bracket was developed. A double-layer adjustment scheme was adopted to satisfy the individual and overall adjustment needs of the acceleration device cavity. For ease of adjustment, the bracket was designed with four-point support, and the optimal support positions were determined through optimized calculations. By analyzing and comparing the deformation of different structural forms of the overall vertical motion plate, the optimized structure of the vertical motion plate was derived. The overall horizontal motion plate was made of thick plates to reduce the height dimension. Additionally, the independent support structure was subjected to verification analysis. Finally, the adjustment accuracy of the bracket was theoretically analyzed to ensure compliance with the adjustment requirements. Through the above analysis and calculations, the theoretical analysis and calculation of a large-span precision adjustment bracket were completed.
