Abstract
In this study, a part of the shafting structure of the accessory transmission system consisting of shaft-gear-bearing is studied. ANSYS/LS-DYNA explicit dynamics simulation software is used to simulate the dynamics of the shaft structure. It compares and analyzes the overall shaft structure, gears and bearings. The simulation results show that: The place where the equivalent stress of the shaft structure is relatively large is mainly concentrated at the tooth root and the tooth surface, where the stress is mainly in the vicinity of two or three teeth. With the change of time, the maximum equivalent stress value and position of the rolling elements are also correspondingly changed, it provides a reference for the design and optimization of gear and bearing in the actual assembly process for transmission system.
Highlights
IntroductionIt is very important to establish a traditional system for shafting and to be able to effectively simulate the interaction between parts of the mechanical system
This study uses a part of the shafting structure of the accessory transmission system consisting of shaft-gear-bearing as the research object
In ANSYS/LS-DYNA software, there is no contact unit, only the surfaces that may be contacted, the contact type and contact related parameters are defined, and the frictional force is taken into consideration
Summary
It is very important to establish a traditional system for shafting and to be able to effectively simulate the interaction between parts of the mechanical system
