The Design and Static Characteristics Finite Element Analysis for High-speed Vertical Machining Center Workbench

To meet the high-accuracy requirement of DVG 850 high-speed vertical machining centerdesigned two different kinds of backstraps structure workbench,analyzed their static characteristics with ansys software and given their formation patternAccording to the analysis results,choose a better workbench structrue.The analysis result is shown that changing the structure of backstraps can improve the workbench stiffness.It makes a base for workbench optimized design.
