Geometric Tolerance Analysis Model of Curved Gate Based on Comprehensive Adjustment
The center line of the orifice is the geometric basis of the installation and fault diagnosis of the arc gate,but it is often faced with difficult problems of preservation and reproduction in engineering.In this paper,the geometric rela-tionship between the embedded parts and the center line of the orifice was synthesized.Based on the conditional adjust-ment theory with parameters,the accurate solution of the center line of the orifice was realized.According to the spatial structure of the curved gate,the coordinate system of geometric tolerance analysis of the curved gate with engineering meaning was established.A geometric tolerance analysis model of the curved gate based on comprehensive adjustment was proposed.The theory and engineering practice show that the proposed analysis model can accurately reproduce the center line of the orifice,and intuitively and efficiently analyze the geometric tolerance of each embedded part,which has strong engineering value and research significance.
