波导丝是磁致伸缩位移传感器的核心元件，其表面质量直接影响传感器的测量精度。为研究波导丝表面质量对检测信号的影响规律，通过建立扭转波在波导丝中传播的力学模型，得到扭转波的波动方程。在此基础上，对2种不同表面状况下波导丝中扭转波的传播开展数值模拟和实验验证。研究结果对今后高精度大量程磁致伸缩位移传感器的研制具有一定参考作用。
波導絲是磁緻伸縮位移傳感器的覈心元件，其錶麵質量直接影響傳感器的測量精度。為研究波導絲錶麵質量對檢測信號的影響規律，通過建立扭轉波在波導絲中傳播的力學模型，得到扭轉波的波動方程。在此基礎上，對2種不同錶麵狀況下波導絲中扭轉波的傳播開展數值模擬和實驗驗證。研究結果對今後高精度大量程磁緻伸縮位移傳感器的研製具有一定參攷作用。

The waveguide wire is the key component of magnetostrictive displacement sensor,its surface quality directly influences measurement precision of sensor. In order to research influence rule of surface waveguide wire on detecting signal,wave equation is achieved by establishing mechanical model of torsional wave propagation in waveguide wire. On this basis,propagation of torsional wave in two different surface quality of waveguide wire is investigated by using numerical simulation and experimental verification. Research results has certain reference effect on development of magnetostrictive displacement sensor with wide-range and high-precision.
