摘　　要：为研究电梯在运动过程中的流动和噪声特性,文中采用数值模拟的方法通过动网格与UDF技术研究了电梯在上升的过程中流场和声场的动态特性;最后得出在电梯上升的过程中电梯周围的流场和声场的变化形式,并且发现随着电梯上升速度的提高,电梯周围流体的流速和产生的声压级都会随之增大。To investigate the flow and noise characteristics of an elevator during its movement,numerical simulations were conducted using dynamic meshing and UDF technology to analyze the dynamic behavior of the flow field and sound field as the elevator ascends.The results elucidate the evolving patterns of the flow and sound fields surrounding the elevator during its upward motion.Notably,it was observed that as the elevator’s ascending speed increases,both the fluid velocity in its vicinity and the resulting sound pressure level rise correspondingly.
