Abstract
As the basis of carrying guide rail operation, beam support mode has been widely used in high-end manufacturing, equipment, mechanical engineering and other fields. With beam support and rotating structure driving position and attitude changes, flexible three-dimensional space movement can be realized.The key technology of the beam support to drive the branch guide rail is to control the deformation of the guide rail. The deformation of the guide rail mainly affects the guide rail structure, stiffness, supporting mode, driver design and load, etc.When the driving mode, driving position and driving force, guide bracket (including bracket and connection mode) and load (including mass load, load moving position and moving range) are determined,Or affected by the use of the requirements of the adjustment range is very small, the beam support mode becomes the main influencing factor of guide deformation, especially in the rotary state of the branch guide, guide force, deformation, deflection and so on will show different trends, such as the maximum deformation of the driving end may be 26 times.This paper through the analysis of the main parameters affecting the guide rail deformation characteristics, the default part, on the basis of mathematical modeling and simulation analysis with Solidworks software, compare a variety of support and attitude under the guide of stress and deformation, gives the relative deformation degree under different mode, can provide a reference for relevant involved.
