| Abstract: | Gear transmission is a common method for radar servo driving system, its torsional vibration can directly influence the response speed and the stability of radar servo system. Aiming at the first level gear transmission system of a radar, based on the software of ANSYS/LS-DYNA, the effects of some mechanical factors such as supporting position, shaft diameter and mass distribution of shaft on the torsional vibration response are studied by the center difference method. Some qualitative conclusions are presented by comparison analysis. The research results will guide further study of radar servo system. |
