摘　　要：叶片腹板粘接胶层厚度预测通常是在叶片试合模过程中压橡皮泥,测量的橡皮泥厚度为腹板粘接胶层厚度。本文提出利用三维激光扫描技术扫描叶片蒙皮和腹板外形,通过模拟合模方式形成合模模型并测量合模腹板间隙的测量方法。本文将通过三维激光扫描对腹板合模间隙进行测量得到的数据与试合模所压橡皮泥的数据进行对比,发现两者测试数据相近,可将三维激光扫描测量作为叶片腹板合模间隙的测量方法,实现免试合模过程,同时分析了影响测量精度的主要因素。The thickness prediction of the adhesive layer on the blade web is usually made by pressing the plasticine during the blade trial closing process.The thickness of the plasticine measured is the thickness of the adhesive layer on the web.In this paper,a measurement method is proposed to scan the shape of blade skin and web by means of three-dimensional laser scanning technology,and to obtain the mold closing die by simulating the mold closing mode,and to measure the die closing clearance of the blade web.In this paper,the three-dimensional laser scanning is used to measure the closing clearance of the blade web,and the measured data are compared with the data of the plasticine pressed by the trial closing die.The 3 D laser scanning measurement can be used as a method to measure the clamping gap of the blade web to achieve the trial-free clamping measurement.This paper analyzes the main factors affecting the measurement accuracy.
