Abstract
This study focuses on the high-precision two-dimensional overloaded precision drive seat.It starts by establishing a three-dimensional model and conducting modal analysis using Ansys software to study the deformation trends of the overall modal shapes.Then,it explores the vibration characteristics of the two-di-mensional heavy-load transmission seat through dynamic simulation using Adams software.The results show that the seat exhibits different vibration characteristics in the XYZ three different directions,with the strongest vibration intensity in the Y direction,followed by the X direction,and the weakest in the Z direction.Finally,the study proposes improvements for structures where vibration signals are concentrated,suggesting a dual-ac-tion backlash-free gear transmission system,and optimizing the internal support structure of the column.Sim-ulations and experimental validations of the optimized structure indicate that the vibration reduction scheme is effective,with a maximum amplitude optimization rate of 47.32%.This research provides references for the design and performance optimization of similar transmission systems,especially in complex systems with mul-tiple components,to enhance the performance and reliability of transmission systems.
