| 8. | The main results show that : ( 1 ) the mechanism of laser bending is very different from that in bending with hard tools . ( 2 ) the bending angle is varied along scanning direction , and there is a deformation wave in the process . ( 3 ) the effects of sheet length on bending can be neglected while the length is more than 10 times of thickness . ( 4 ) the sheet width has much higher influence on the bending process
分析发现：激光弯曲成形时板料的应力状态与机械折弯时有根本不同；当激光束沿直线单向扫描时，板料两端的弯曲角度不同；板料的长度大于10倍板厚或5倍光斑尺寸时，板长对弯曲角度的影响不再显著；沿扫描方向，距离光斑中心3倍光斑尺寸以外的区域，仍然对弯曲变形量产生影响。 |
