Keywords: AGV, modal analysis, lifting mechanism, ball screw, ANSYS Workbench Abstract:In this paper, the engine lifting mechanism of engine assembly line AGV is as an example, the engine lifting mechanism model is established using solidworks software, and using ANSYS Workbench 14.0 software the modal is analyzed of lift mechanism and ball screw to obtain their first 6 node frequencies and mode shapes. Designed to avoid co-channel interference caused by the lifting mechanism and screw resonance. The results show that low-level engine lifting mechanism modal frequency and vibration amplitude are small, and the gap with the drive motor frequency is very large. The structural meets the design requirements, a method and basis is provided to enhance the design and improvement, and then for the lift mechanism of AGV design provides important scientific guarantees.
