摘要
为了解决复合材料桨叶的静力矩测量结果差异较大、难以完成准确合格性判定等问题,采用基于天平基本理论的控制变量法对多组桨叶的静力矩展开研究.通过分析造成实验数据差异的原因,结合测量设备本身的精度,发现了对测量影响较大的关键因素,并进行了定量分析计算.通过对比实验,证明了对大轴线力矩测量影响最大的是定位面与测量刀口之间的距离以及其平面加工精度;对小轴线力矩测量影响最大的是对桨叶特定截面的角度测量精度.本研究为后续螺旋桨设计、生产、维修提供了工艺优化的理论和数据基础,对后期新型桨叶的研发具有重要意义.
Abstract
In order to solve the problem that the static moments of composite paddles are widely varied and it is difficult to make an accurate qualification evaluation,the static moments of multiple sets of paddles are investigated by using the control variable method according to the basic theory of the balance.By analyzing the differences caused in the experimental data and considering the accuracy of the measuring equipment itself,the main factors that have a greater impact on the measurement are discovered with quantitative analyses and calculations.Through comparative experiments,it is proved that the greatest influence on axial torque measurement is the distance of the positioning surface from the measuring cutter and its flat machining accuracy.The greatest influence on radial torque measurement is the angular measurement accuracy of the specific section of the propeller blade.This study provides a theoretical and data basis for process optimization for subsequent propeller design,production and maintenance,and is significant for the research and development of new propeller blades in the future.
