Design Optimization of Hydrostatic Bearing Pad in Computer Numerical Control Double-Head Milling Machine for Rotor Process and Its Application
摘要
Abstract
During the machining of nuclear power turbine rotors in Shanghai Turbine Plant,the imported Computer Numerical Control(CNC)double-head milling machine frequently experienced lifting failures with its original hydrostatic bearing pads during blade groove milling.This was attributed to insufficient material strength and structural design flaws in the pads,which severely constrained production efficiency.To address this issue,a systematic analysis of the hydrostatic bearing pad structure on the Ingersoll CNC double-head milling machine was conducted using Shanghai Turbine Plant A907 nuclear power low-pressure rotor as the research objective.Improvements were carried out focusing on oil cavity structure,bearing pad material selection,and oil pressure parameter calculation.Concurrently,statics simulation was performed using ABAQUS software,followed by on-site verification.The results demonstrated that the optimized hydrostatic bearing pad could meet the oil pressure requirements and the rotor lifting height specifications during actual machining,and the lifting failure problem was effectively solved.These research findings can provide technical reference for the design optimization of hydrostatic bearing pads in the machining of similar rotors.关键词
