一、波纹板的弯曲工艺性分析图1所示波纹板由19段等径圆弧相切，模拟正弦波形，共有9个槽，两端直线段与圆弧相切并弯成直角而组成、其材料为1Cr18Ni9Ti，厚度t=3mm，弯曲线长度B=2400mm。材料的抗拉强度бb=60kgf／mm~2，屈服点бb=20kmf／mm~2，弹性模量E=20000kgf／mm~2。波 First, the corrugated board bending process analysis The corrugated board shown in Figure 1 consists of 19 sections of equal circle arc tangent to simulate the sine waveform, a total of nine slots, both ends of the straight line tangent and arc tangent and composed at right angles, The material is 1Cr18Ni9Ti, thickness t = 3mm, bending length B = 2400mm. Material tensile strength бb = 60kgf / mm ~ 2, yield point бb = 20kmf / mm ~ 2, elastic modulus E = 20000kgf / mm ~ 2. wave
