摘要
Abstract
To address the operational performance issues of swing cylinders in ultra-low temperature environments,this study focuses on the selection and matching of low-temperature materials.By simplifying the screw pair engagement into a planar model,fluid-structure interaction simulations are conducted on the oil film of the swing cylinder′s screw pair,analyzing the effects of different shaft speeds,circumferential clearances,and oil viscosities on oil film performance.A test bench is built to verify the operational performance of the prototype in ultra-low temperature environments,with comparisons of swing cylinder speed variations under different temperatures.The experimental results indicate that using low-temperature hydraulic oil can appropriately improve the transmission efficiency of swing cylinders in ultra-low temperature environments,laying a technical foundation for solving driving and control engineering challenges of related equipment in extreme environments.关键词
