The Deformation Analysis about Guide Way Contact of Large Span and Heavy Load Cross-Rail
The article used the large span and heavy load cross-rail of some machine tools plant’s heavy-type numerical control milling planer for research object, by using the finite element software to build the model and force analysis. It also researched the force distribution and deformation condition of the large span motion girder under the actual working condition. It considered the slide carriage superposition effect to build the describing method and establishing process of the large span load curve by contacting analysis and restraining analysis, and got the knifepoint trajectory deformation. The research provided the sufficient theory basis and simulation method for designing improvement of cross-rail structure and got a perfect arch in advance.
