剪切角关系.doc

金属切削原理课题：剪切角，相对滑移，变形系数三者间关系的探讨根据剪切角与剪应变即相对滑移的函数关系，剪切角与变形系数的函数关系，讨论选择在不同前角时，画出剪切角与相对滑移，变形系数的关系折线图。学生姓名：杨程建班级：10切削1班学号：10050202002剪切角，相对滑移，变形系数三者间关系的探讨一、函数关系式剪切角与剪应变即相对滑移的关系：；剪切角与变形系数的关系：；二、不同前角时相对滑移，变形系数关系选取分别为15度、45度、75度时的三者间关系图如下：在前角相同时，相对滑移随着剪切角的增大而减小（在前角为15度时相对滑移先减小后增大）；在剪切角相同时，前角度数越大，相对滑移越小。而且前角度数越大，相对滑移减少的速率相对较小。在前角相同时，变形系数随着剪切角的增大而减小，在剪切角0.2rad时减小的快，之后减小的速度比较慢。当剪切角（0.8rad=）小于时，变形系数随前角的增大而减小；当剪切角大于时，变形系数随前角的增大而增大。当时(rad)0.08722210.597388.7964320.1744444.974474.72070.2616673.1570353.3482360.3488892.2829522.6514290.4361111.7819752.2247010.5233331.4653061.9328090.6105561.2528541.7177460.6977781.1051661.5504640.7851.0007961.4147770.8722220.9272981.3009280.9594440.8771681.2026571.0466670.8458651.1157371.1338890.8307781.0371811.2211110.830710.964791.3083330.8456570.8968731.3955560.8768030.8320731.4827780.9267430.769251.5710.707388当时(rad)0.0872228.6936883.9329070.1744443.5329272.4379860.2616672.0041041.9345860.3488891.3223211.6790070.4361110.9550631.5224890.5233330.7339091.4154270.6105560.5905931.3365450.6977780.4928641.2751890.7850.42381.2254210.8722220.3738151.1836620.9594440.3371631.1476181.0466670.3102511.1157371.1338890.2907721.0869241.2211110.2772281.0603721.3083330.2686611.0354611.3955560.2645011.0116931.4827780.2644820.988651.570.2686030.96596附录表：当时（rad）0.08722211.2596411.305290.1744445.5867735.7397590.2616673.7340323.8656180.3488892.8364352.9141070.4361112.3219812.3313960.5233332.000921.9328090.6105561.7928591.6391350.6977781.6586491.4107050.7851.5777931.2254210.8722221.53961.0699560.9594441.5394290.9357641.0466671.5772620.8170721.1338891.6576910.7098021.2211111.7913410.6109491.3083
