摘要:

针对目前位移传感器很难直接测得木结构或木构件在转动中产生较大绝对水平位移的问题，研制了量程为±500 mm的电阻应变式位移传感器（WD位移传感器），应用正交试验法分析WD位移传感器的影响因素，并对其进行设计与制作，拟合了传感器在不同量程下应变位移的分段函数关系，通过计算得出了WD位移传感器的6种静态参数指标。试验结果表明，WD位移传感器克服了传统电阻应变式位移传感器量程小的问题，解决了木结构或木构件发生非直线运动很难直接测得绝对水平位移的问题，且各静态参数指标良好。

关键词:位移传感器;正交试验;应变-位移函数;静态参数

Abstract:

WD displacement sensor with a range of ±500mm is developed in order to measure large horizontal displacement. And the parameters analysis of WD displacement sensor are carried on using the orthogonal test method. The strain-displacement relationship of sensor is obtained. Six static parameters of WD displacement sensor are calculated. The experimental results showed that WD displacement sensor could measure the non-linear large displacement which is difficult to be measured directly by traditional electrical resistance sensor and all the static parameters are in good condition.

Key words:displacement sensor;orthogonal test;strain-displacement relationship;static parameters
