The Study On Relationship Between Structures And Properties Of Linear Guide Pair

Linear guide pairs are widely used to guide,support,locate,and accurately move machinery components and products in a wide range of automation applications.Linear guide pairs provide low friction,smooth,accurate motion for nearly any moment or normal loading condition.Major applications include factory automation,medical,packaging,machine tool,semiconductor,printing,automotive assembly,aerospace and food processing.The relationship between structure and properties of linear guide pairs are researched in this work.The linear guide pairs are chosen for experiment.Vibration and stiffness properties of linear rolling guide pair are taken as main properties.Five linear guide pairs are chosen for experiment:three are ball circulating type and two are roller type of linear rolling guides.The product of abroad company-1,abroad company-2,Chinese company-1 and Chinese company-2 are taken.The stiffness is measured experimentally and proved by FEA analysis.The simulation analyses are done by Ansys Workbench 14.0.The stiffness is proved by Static Structural simulation analysis.The FEA prediction and experiment results are compared and explained properly.Through the hammer impact test the natural frequencies of linear guide pairs are measured.All five linear guide pairs are examined.The results of hammer impact test are discussed and explained.The natural frequencies of models are predicted by Ansys Workbench.FEA results are discussed and compared with each other.The experiment and the FEA prediction are compared.The 3D models of linear rolling guides are built up in Proengineer.The geometric parameters are taken from each company’s handbook.For simulation the models are transferred to Ansys Workbench.For concluding the study,after all analysis the new structure of linear rolling guide was set up by Proengineer.For analyzing the relationship between structure and property of new structure the 3D model was examined in Ansys Workbench.The static structural and modal analyses are done by FEA.The twelve different parameters are examined theoretically in Ansys workbench.The main three geometrical parameters of linear guide pair is changed to different sizes and examined.The ideal geometrical parameters are obtained through the simulation prediction.
