Study on significant factors of stable dynamic stiffness and advanced assembly for precision fastening system by Taguchi method

Abstract Precision assembly fastening is an indispensable part of technology. The clamping force the precision system maybe remain Table or decrease when subjected to axial vibration. In meantime, rotating for a long time at very high speed will produce temperature. When temperature rises, it greatly reduce overall performance and accuracy fasten system. With background this problem, research was started. study, experiments were carried out with rotation dynamic percussion testing machine, Taguchi method used discuss different parameters conditions. experimental control factors are fitting clearance, bearing contact angles, viscosity lubricating oil. After getting test value, next step statistical analysis using in stages get final optimal results experiment. showed that angle oil important affecting rise bearing. experiment can be applied as basis assembling machine tools advanced manufacturing industry, aircraft automotive light vehicles heavy mining world, etc. This also aims improve stability
