摘　　要：基于叶片型面磨削工艺参数及工艺过程确定机床各坐标轴运动性能和磨削接触压力,进行叶片加工砂带磨床优化设计和频率分析。采用RTCP算法和传动链独立的算法结构模式,建立转轴数学模型、工件传动链算法库以及刀具传动链算法库。对设计的机床伺服速度进行测试,优化机床结构薄弱环节,满足叶片型面及全特征型面磨削要求。通过有限元分析研究X,Y,Z轴的变形量,计算六轴砂带磨床1阶~6阶的固有振动频率,并进行分析和优化,提高了叶片磨削的轮廓精度,加工经济效益显著。Based on the grinding process parameters and process of blade profile,the motion performance and grinding contact pressure of each coordinate axis of the machine tool are determined,and the optimized design and frequency analysis of the blade machining belt grinder are carried out.Using the RTCP algorithm and an independent algorithm structure mode for the transmission chain,establish a mathematical model for the shaft,a library of calculation methods for the workpiece transmission chain,and a library of calculation methods for the tool transmission chain.Test the servo speed of the designed machine tool,optimize the weak links of the machine tool structure,and meet the grinding requirements of blade profile and full feature profile.By studying the deformation of the X,Y,and Z axes through finite element analysis,the natural vibration frequencies of the first to sixth order of the six axis abrasive belt grinder are calculated,analyzed,and optimized,which improve the contour accuracy of blade grinding and achieve significant processing economic benefits.
